工程力学作业4(国外英文资料) 4 tutorial of engineering mechanics (Ben) One, single choice question The free term in the fundamental equation of the displacement method, which represents the force of the load under the basic system (C. The graph of the bending moment is shown in the diagram. The coefficient in the equation of the structural displacement equation is (D. 8). To make the Angle = 0 of the diagram node A, the force M = (C.) should be applied at node A. The bending moment = (C.) of the B side of a continuous beam. The direct object of the torque distribution method is (A. The result of A convergence of the calculation structure of the torque distribution is because (a. the distribution coefficient is less than 1). The continuous beam is shown in the image below. The torque applied at the end of A is required by the torque applied by the A. The passing moment of the bar is associated with (D.) When using displacement method to calculate the superstatic structure, the basic unknown quantity is (D. Node displacement). The three beams are the same as the length of the three beams, and their fixed end moments are the same as (C. (2), (3) the fixed end bending moments. The freedom in the equation of the structure displacement equation = (B. -2) The B side rotation stiffness of the structure bar BC is (d. 8). The sum of all the vertices of the pole of A single node is equal to (a. 1) What are the factors of the torque transfer coefficient C that is equal to the following? (c. distal) The distributive bending moment is (the A) moment that occurs when A is rotated. This is MAD (a.1kn ? m). In the calculation of displacement, the bending moment of the positive lever is (A. The typical equation of displacement method is essentially (a. equilibrium equation) The number of basic unknowns with displacement method (A) is related to the form of the structure. The coefficient representation in the typical equation of the displacement method is generated by the basic system (C. The sol
