A rigid bar AD is hanged by two steel cables of diameter 0.065 in as shown in the figure. Find: a) The tension force in the cable BE • and cable CF when P=220 Ib b) The deflection at Point D (6) Est=29*106 Psi F S in E 10 in B

A horizontal beam AB with dimensions of its cross section (b = 19 mm) x (h = 200 mm) is supported by a rake CD and supports a load P = 12 kN at B (see part a of the figure). The strut, consisting of two bars each with a thickness of 5b/8, is connected to the beam by a bolt that passes through the three bars that meet at C (see part b of the figure)   (a) If the allowable shear stress in the bolt is 90 MPa, what is the necessary minimum diameter (dmin) of the bolt at C? (b) If the allowable bearing stress in the bolt is 130 MPa, what is the necessary minimum diameter (dmin) of the bolt at C?
