Problem 914 | Combined Axial and Bending

Problem 914
The structure shown in Figure P-914 is hinged to fixed is hinged to fixed supports at A and C. Assume that the pin connections at A, B, and C are frictionless. The bars are each 4 in. by 4 in. in section. Compute the maximum compressive stress developed in bar AD.



Solution 914




a block weighting 1000N is

a block weighting 1000N is kept on a rough plane inclines at 40 digress to the horizontal the coefficient of friction between the block and the plane is 0.6.Determine the smallest force inclines at 15 digress to the plane required just to move the block up the plane.
