Problem A uniform plate weighing 100 lb is supported by a ball-and-socket joint at O, a fixture providing only vertical reaction at A, a wire EF, and a spring of constant k at C. If the unstretched length of the spring is 6in, what should the spring constant be, so that equilibrium is maintained in the configuration shown? (Note: Force in the spring k (stretched length - unstretched length). 16 .4 B 16" 18 y 18" 24 10

Problem 2: The figure below shows a two-member plane truss supported by a linearly elastic spring. The truss members are of a solid circular cross section having diameter, d = 20mm, and E = 80 GPa. The linear spring has a stiffness constant of 50 N/mm. A load of 15 kN is applied at 3 at an angle of 50 degrees with the horizontal. Find (a) The global displacements of the unconstrained node and (b) compute the reaction forces and...
