Try to draw the free-body diagram for the roller or wheel support with lateral constraint, which is shown in Fig.3/8.3.(15%) 2. For several 3-D parallel fprces acting on a rigid body as shown in Fig.3/9.3, try to set up the associated equations of equilibrium (15%). 3. The welded tubular frame is secured to the horizontal x-y plane by a ball-and-socket joint at A and receives support from the loosing-fitting ring at B. Under the action of the 2-kN load, rotation about a line from A to B is prevented by the cable CD, and the frame is stable in the position shown. Neglect the weight of the frame compared withe the applied load and determine the tension T in the cable, the reaction at the ring, and the reaction components at A (25%). 课本p.152图 4. What is the plane truss? Try to write the required equation of equilibrium when method of joint is used to determine the internal forces in all members within it (25%) 5. Determine the forces in members BC and BG of the loaded truss.(20%) 例题 4/15 图 --
