The teaching plan for the college of architectural mechanics generally included the following contents: * * I. Teaching Purpose Requirements ** 1. * * Master the content ** - The concept of a rigid body and the basic form of rod transformation. For example, the basic forms of bar transformation include tension, compression, shear, twist, and bending. Students need to understand the force characteristics of the bar under these forms of transformation. 2. * * Familiar with the content ** - The types of planar bar structures, such as beams, and other common types of structural characteristics, etc. - The tasks of architectural mechanics included the structural composition (the rationality of the structure composed of bars, etc.), the calculation of the internal force of the static structure (under the action of load, the internal force calculation when the bar is regarded as a rigid body), the relationship between the force and the displacement of a single bar under basic displacement (considering the bar as a deformed body), the displacement and displacement of the static structure under load, the calculation method of the internal force (displacement) of the over-determined structure, and the stability of the straight bar under pressure. - The rigid body, the deformed body and their basic assumptions, such as the assumption of continuity, equality, and isopy of the deformed body, etc. 3. * * Understand the content ** - The concepts of thin-wall structures and solid structures were not important, but it would help students to have a more comprehensive understanding of building structures. - The classification of loads was focused on concentrated loads and uniformly distributed loads. The other types of loads could be further understood in the subsequent courses. * * 2. Teaching Points and Difficulties ** 1. * * Teaching Focus ** - The basic form of the member's distortion was the key point, because it was the basis of many subsequent contents. For example, the structural design should consider the distortion form of the member under different loads to determine the safety of the structure. 2. * * Teaching Difficulties ** - The rigid body, the deformed body, and their basic assumptions were difficult to understand. A rigid body was an ideal model that would not be deformed under force. It was used to simplify certain problems. The assumption of a deformed body was the key to studying the actual force and transformation relationship of the rod. Students needed to understand the conversion and application of these concepts in different analysis situations. * * 3. Teaching methods and teaching methods ** Lectures, discussions, and case-based teaching methods can be used. Lectures were used to explain basic concepts and theories, such as the concept of rigid body and the form of rod transformation. Discussions could be used to discuss the application of structural mechanics in some practical engineering cases to stimulate students 'thinking. Case-based teaching allowed students to better understand the application of architectural mechanics knowledge in practice through practical building structure cases, such as bridge structure force analysis. * * 4. Teaching hours ** Generally, four class hours are arranged, and the details can be adjusted according to the depth and breadth of the course content and the students 'acceptance ability. * * 5. Explanation of specific knowledge points ** 1. * * Rod structure ** - The skeleton of a building was mostly composed of bars. The main research of architectural mechanics was the planar bar structure, which was represented by its axis in the calculation diagram. For example, when analyzing frame structures, the structural model was simplified with the axis of the bar, which was convenient for mechanical analysis. 2. * * Calculation Model ** - A rigid body is an object that will not be deformed by force. It can simplify the problem when it has nothing to do with the transformation or when the influence is small. For example, when analyzing the overall force balance of a static structure, you can first treat the rod as a rigid body for analysis. - The deformed body is a discussion of the non-negligible transformation of an object, and it must follow the assumptions of continuity, equality, and isopericity. 3. * * Basic Transformation Form ** - For example, the columns in the building may produce tension-compression distortion when they are subjected to a vertical load. Students should understand the calculation method of the internal force of the bar (the axis force) during the tension-compression distortion. - Shearing distortion. Shearing distortion may occur in a connection such as a bolt connection. It is necessary to master the calculation of the shear force on the shear surface. - Torsional distortion, like some shaft components that are subjected to a twisting force, such as the transmission shaft in machinery, some special structural components in buildings may also have a twisting distortion. You have to learn to calculate the twisting moment. - Bending and distortion. Beam structures will bend and distort under the effect of a horizontal load. You need to master the calculation of bending moment and shear force, as well as the calculation of bending stress and distortion of the beam. 4. * * Other contents of architectural mechanics ** - When the structure was composed of bars, it was necessary to study how to form a reasonable structure, such as the connection method of different bars and the influence of structural layout on the overall structural performance. - In terms of the load bearing capacity of the structure, in addition to the internal force calculation of the static structure mentioned earlier, it also involved the calculation methods of the internal force (displacement) of the over-determined structure, such as the force method, displacement method, moment distribution method, etc. - When studying the transformation of a single bar, it was necessary to explore the quantitative relationship between the force and the transformation, such as the application of Hooke's law in tension and compression. - The calculation of the displacement of a static structure under load was very important for evaluating the adaptability of the structure. - The stability of a straight bar under pressure required an understanding of the possible instability of a slender straight bar under pressure and how to calculate the critical pressure. 5. * * Type of load ** - Focus on concentrated load and uniform load. The concentrated load is like a concentrated force acting on the beam, and the uniform load is like a surface load or a line load evenly distributed on the beam. It is necessary to master the calculation method of the internal force and displacement of the structure under these two kinds of loads. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In Kunming, the price of Bilan photography was at a moderate level. For example, their wedding photos had a package worth 5000 yuan (original price 6999 yuan), including a variety of services and products; In terms of photo prices, compared to ancient photography (2000 - 4000 yuan), the small Ximen studio shot a set of photos for about 4500 yuan, and there were hundreds to thousands of photos to choose from. Overall, it was not expensive than blue photography. However, there were also opinions that compared to some relatively cheap photography agencies, Blue photography might not be cheap. At the same time, some people felt that there were more expensive photography agencies in Kunming, so whether the price was expensive or not depended on different comparison targets and consumer expectations. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The lyrics of " The Myths " sung by Chan were as follows: " Unlocking my most mysterious wait, the stars are falling, the wind is blowing, and finally I hold you in my arms again, my two hearts tremble. Believe in my unchanging sincerity. I have promised to wait for a thousand years. No matter how many winters pass, I will never let go." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following were some of the master-themed novels that changed the world behind the scenes: " Lord God's Avenue "," Raising All Humans "," Low-Dimensional Games "," I Draw a World "," Creating a Real World "," My Players Can Become Gods "," Creating a Sandbox World "," Lord God's Rise "," Players 'Supreme Justice ", etc. However, whether the names sounded good or not was subjective. For example," Lord God's Avenue " gave people a grand and mysterious feeling, while " Raising All Humans " was more novel and unique. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

You may have misunderstood that The Monster World Trilogy is a movie, not a novel. There wasn't enough information to say whether the movie was " good," because " good " was a subjective evaluation standard. Different people had different preferences for the movie. Some people might like its sci-fi, adventure, action elements, and the prehistoric world and various monsters it showed. Others might not be interested in such topics. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
