The block has thickness t 5 1 in. and width b 5 3 in. (a) If the diameter d of the cable is 0.25 in., what are the maximum tensile and compressive stresses s t and s c , respectively, in the block? (b) If the diameter of the cable is increased (without changing the force P ), what happens to the maximum tensile and compressive stresses? b t P P A-PDF Split DEMO : Purchase from www.A-PDF.com to remove the watermark...
