Problem 1 In Figure 1, the spring has an unstretched length of 0.2 m, and the uniform bars, AB and BC, each have a mass of 30 kg. The mass of the members is not ignorable in both questions below (assume gravity = 10 m/s² for this problem). (a) Determine the angle 0 for equilibrium. Note that you cannot use the method of virtual work for this problem. (b) Determine the normal force, shear force and bending moment at point D. A 2 m 0 B k =200 N/m Ꮎ D Figure 1 1 m

3. Two beams are supported as shown in the diagram below, each 150mm x 200mm x 4 meters. Beam CD is a cantilever beam carrying a uniformly distributed load of 4 KN/m freely supported on beam AB. Beam AB is freely supported on each ends. E = 13.8 GPa for both beam. Neglect the weight of the beam. a. Compute the reaction at D. b. Compute the deflection at D. c. Compute the bending stress of beam CD. 4kN Im 4m 4m

Solve step by step.. Thanks

Figure Q2 shows a statically determinate plane truss subjected to a horizontal concentrated load at B. The truss is made using steel with Young's modulus of 205 GPa, and the cross section area for all members are constant. If the horizontal displacement at B is limited to 10 mm, determine the minimum cross section area required for the truss. The solution can be based on Method of Conservation Energy or Method of Virtual Work. (а) (b) Based on Q2(a), suggest an appropriate steel bar measurement.

The lower ends of the three bars in the figure are the same level before the rigid homogeneous W=100 kN block is attached. The properties of the bars are shown in the table. The temperature of the bars is then increased by 80°C. The block is assumed to remain horizontal after all deformations have occured. a.) Which of the following most nearly gives the temperature rise to cause all of the applied loads to be supported by the steel rods? b.) Which of the following most nearly gives the stress developed in the bronze bar? c.) Which of the following most nearly gives the stress developed in the steel bar?

Question 6 A straight bar is fixed at edges A and B. Its elastic modulus is E and cross section is A. There is a load P = 100 N acting at C. The magnitude of the reactions at the ends A and B are L с P = 100 N 2L B
