Second, multiple-choice questions (10 points each, 40 points in total) 6. The degree of freedom of an industrial robot depends on the movement required by the target. 7. For an industrial robot that only worked on a two-dimensional plane, it only needed three degrees of freedom. To make the operation have a random pose, the industrial robot needed at least six degrees of freedom. 8. An industrial robot that worked on a two-dimensional plane required three degrees of freedom. 9. The Delta mechanism referred to a type of robot. Third, comprehensive questions (10 points each, 20 points in total) 13. The process and principle of signal transformation and transmission in the computer control system as shown in the figure are analyzed and explained. The sample process is the process of using the sample switch (or the sample unit) to sample the simulated signal into a dispersed simulated signal at a certain time interval. Because the scattered simulated signal obtained after the sample was essentially still an simulated signal, it was not digitized and could not be directly sent to the computer. Therefore, it still needed to be digitized and turned into a digital signal before it could be accepted and processed by the computer. 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>
