Member ABCD in Fig. lies in the plane of the paper. If length L is large compared with the depth of the member determine the pin reaction V at D and the horizontal displacement qH of the pin at D. Ans. V 81P 128 qH 9PL3 64EI . Let the pin at D for member ABCD in Problem be prevented from displacing horizontally as load p is applied. Determine pin reactions V and H at D. . The structure in Fig. is made up of a steel E 200 GPa rectangular beam ABC with depth h mm and width b mm and two wood E GPa pin-connected members BD and CD with square cross sections. If load p kN is applied to the beam at c determine the reaction V at support D and the maximum stresses in the steel beam and wood members. Ans. V kN 7beam MPa ơcompression member MPa Figure PROBLEMS 223 . Member ABC in Fig. has a uniform circular cross section with radius r that is small compared with R. Determine the pin reaction V at c and horizontal component of the displacement of point B. . Member ABC in Fig. has a right angle bend at B lies in the x z plane and has a circular cross section with diameter d that is small compared with either length Li or length L2. The reaction at c prevents deflection in the y direction only. Determine the reaction V at c when the moment Mo is applied at c. Ans. V MO 3L22 6L1L2 1 v 2L 2L32 6LiLị l v Figure . Member AB in Fig. is a quadrant of a circle lying in the x z plane has a circular cross section of radius r which is small compared with R and is supported by a spring spring constant K at B whose action line is parallel to the y axis. Determine the force in the spring when torque To is applied at B with action line parallel to the negative z axis. . The structure in Fig. has a uniform circular cross section with diameter d which is small compared with either H or L. The structure is fixed at 0 and c and lies in the x z plane.
