During the stretching process of low-carbon steel, the stress at the yield stage was almost constant. The answer was B. 5. In the stretching process of low-carbon steel, the elastic stage was characteristic of stress and strain being proportional. The answer was A. 6. In the stretching process of low-carbon steel, Hooke's law holds true in the elastic stage, and the answer is A. 7. The maximum stress that a low-carbon steel material can withstand during the tension test is the strength limit, and the answer is C. 8. The moment of inertia of a circular cross section with a diameter of D is (Pi D/64). 9. The ability of a component to resist distortion was called stiffness, and the answer was A. 10. The ability of the component to resist damage was called strength, and the answer was B. Second, the answer to the true and false question: 1. The basic forms of rod distortion were: axial-direction stretching and compression, cutting, twisting, and bending. 2. The internal force coinciding with the axis during the axial-direction stretching (compression) is called the axial-force, not the shear-force. Wrong. 3. The normal stress of the beam is caused by the bending moment, not the shear force. Wrong. 4. The magnitude of the normal stress of the axial-direction stretching (compression) is directly proportional to the magnitude of the axial-force. Correct. 5. The moment of inertia of any plane figure about a certain axis must be greater than zero, correct. 6. Among the moments of inertia of a plane figure with respect to all parallel axes, its moment of inertia with respect to the center axis is the smallest. Wrong. 7. The moment of inertia of any plane figure about a certain axis is always greater than zero, error. 8. The moment of inertia of a plane figure about any axis is equal to the moment of inertia of the center axis parallel to the axis plus the product of the area of the plane figure and the square of the distance between the two axes. Correct. 9. The greater the tension and compression stiffness, the stronger the ability of the bar to resist the vertical distortion. 10. Hooke's law applies to elastic materials. Wrong. Third, the answer to the calculation question: 1. Since the specific structure and force diagram of the bar were not given, the axis force diagram of the bar could not be accurately drawn. 2. Since the specific structure and stress diagram of the bar were not given, it was impossible to accurately draw the axis diagram of the steel bar and calculate the maximum normal stress. 3. Since the specific structure and force diagram of the bar were not given, the strength of the bar could not be accurately checked. 4. Since the specific structure and force diagram of the suspension AB were not given, the shear force and bending moment of the C section could not be calculated. Read more exciting novels for free

Civil Engineering Mechanics Form Test Mission 4
The 24th Spring of the National Open University, Civil Engineering Mechanics (This), Form Examination Homework 4 mainly included the following contents: ##1. Multiple-choice questions (3 points for each question, 30 points in total) 1. In the calculation of displacement method, the positive bending moment at the end of the bar is to make the lower side of the beam pull. 2. The coefficient in the typical equation of the displacement method represents the constraint reaction force in the ith additional constraint generated on the basic system. 3. The number of basic unknowns of the displacement method and the number of basic unknowns when solving the structure with the displacement method needed to be analyzed and judged according to the specific structural diagram. 4. The free term in the structural displacement equation, the fixed-end bending moment of the single-span indeterminate beam, and the distributed bending moment were calculated by the corresponding calculation formula in combination with the structural characteristics. The distributed bending moment was the bending moment of the B-end produced when the A-end rotated. 5. In the moment distribution method, the transfer coefficient C is related to the remote support; the unbalanced moment of the continuous beam node B needs to be calculated according to the relevant load and structural conditions. In general, the unbalanced moment of the node is always equal to the sum of the fixed end bending moments of the node. ##2. True or False Questions (3 points per question, 30 points in total) 1. The basic unknown quantity of the displacement method was related to the number of indeterminate times, but the displacement method could calculate the static structure, so this statement was wrong. 2. The basic structure of the displacement method was a hyperstatic structure, which was correct. 3. If the reaction force (moment) in the additional constraint of the basic system of the displacement method was equal to zero, then the basic system was consistent with the original structure, so the original statement was wrong. 4. The free term in the typical equation of the displacement method was the reaction force on the additional constraint under the action of external factors. This statement was correct. 5. The displacement method could be used not only for hyperstatic structures but also for static structures, so the original statement was wrong. 6. In the calculation of the moment distribution method for multi-node structures, it is correct to relax all the non-adjacent nodes at the same time to accelerate the convergence speed. 7. In the moment distribution, when the far end is a directional support, the transmission coefficient is 0. This statement is correct. 8. In a given continuous beam, the unbalanced moment of node B needs to be calculated according to the specific bending moment value. 9. In the moment distribution method, when the far end is a directional support, the transmission coefficient is 1, which is wrong. 10. The moment distribution method was applicable to continuous beams, which was correct. ##3. Calculation questions (10 points for each sub-question, 30 points in total) 1. For example, using the displacement method to calculate the rigid frame: - Basic unknown: determine the basic unknown of the rigid frame (such as the angular displacement of only one node B). - [Basic System: Add additional rigid arms to a specific point (such as point B) to restrict its rotation to obtain the basic system.] - The displacement equation: List the equation. - Calculating the coefficient and free term: By making some values, the corresponding graph is used to assist in the calculation. The node is taken as the research object, and the coefficient and free term are calculated according to the equilibrium condition. Finally, the equation system is solved to obtain the result. 2. The calculation of other rigid frames or continuous beams followed similar steps, including determining the basic unknown variables, the basic system, listing the displacement equation, and then calculating the coefficient terms and free terms. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Beijing Normal University Online Education General Psychology homework answer
An example of the homework answer is as follows: 1. Perceptive motion stage: When the human eye perceives an object, the brain has already begun to process the information and convert it into visual motion signals. This signal is converted into electrical signals through the retina and transmitted to the brain. At this time, the human eye is in the perceptual motion stage. Perception stage: When the human eye receives electrical signals from an object, the brain will process this information and transform it into visual perception. This perception is processed through the cerebral region of the brain. 3. Memory stage: In the perceptive movement stage and perceptual stage, the information in the human brain has been transformed into memory and stored in long-term memory. Forgetting curve: The forgetting curve refers to the gradual change of the degree of forgetting information in the human brain over time. This change shows a trend of fast first and then slow. Learning effect evaluation: Learning effect evaluation can be carried out through examinations, homework, etc. Usually, standardized evaluation standards are used to ensure the fairness and accuracy of the evaluation results. The above is a brief answer to the general psychology homework of Beijing Normal University's online education. I hope it will be helpful to you.

This kind of task usually required a detailed interpretation and analysis of literary works, combined with relevant language knowledge and literary theory to discuss. We should analyze the Form Test mission from the following aspects: 1. The language elements of literary works. Language is the core of literature, so it is very important to analyze the language elements of literary works. In the task of the Form Test, we should analyze the language in the literary works from the aspects of vocabulary, grammar, rhetoric, etc., and combine it with the knowledge of language to explore the characteristics of the language and its influence on the works. 2. The structural elements of literary works. The structure was an important part of a literary work, and it was also another aspect that needed to be considered in the form test. When we analyze the structural elements of literary works, we should pay attention to the overall structure of the work, the arrangement of the plot, the shaping of the characters, etc., and explore its structural characteristics and functions in combination with the historical and cultural background. 3. The theme of a literary work. The theme was an important part of a literary work, and it was also another aspect that needed to be considered in the form test. When analyzing the theme of a literary work, we should pay attention to the theme of society, history, culture and other aspects of the work, and explore the characteristics and significance of the theme with relevant theories. 4. The influential elements of literary works. Impact was an important part of a literary work, and it was also another aspect that needed to be considered in the form test. When we analyze the influential elements of literary works, we should pay attention to the influence of the works on later generations of literature and the influence on the society at that time. We should also discuss the enlightenment and influence of the works on later generations in combination with the historical and cultural background. In short, we should analyze the language, structure, theme and other elements of the literary works in a comprehensive and in-depth manner. We should combine the relevant language knowledge and literary theory to explore its characteristics, meaning and value in order to have a positive impact on the development of literature.
Mature performance is to open the homework
" Mature performance is to think about homework." This sentence expressed a common phenomenon in growing up in a relaxed and humorous way-learning to accept and deal with academic pressure. As a veteran user of online novels, I deeply understand this feeling. In the past, we might not be able to sleep at night because of an assignment, worried that we might not be able to complete it or that we might not meet our expectations. However, as we grew older and accumulated more experience, we gradually understood that " opening up " was actually a manifestation of wisdom and strength. This " letting go " did not mean giving up or escaping, but learning to adjust his mentality and arrange his time and energy reasonably. When we realize that homework is only a part of the learning process and not the whole of life, we become more calm and mature. We are no longer overwhelmed by the difficulty of homework, but can actively face it and find a solution to the problem. At the same time," opening up " also meant that we began to know how to weigh the pros and cons and stop wasting too much energy on unnecessary things. We know how to prioritize important and urgent tasks, and how to allocate time and energy to complete various assignments. Therefore," the performance of maturity is to open your homework." This sentence not only contained feelings for growth, but also revealed expectations and confidence for a better future! The novel " Flower in the Heart " is equally exciting.
