Link AB, of width b = 2 in. and thicknesst = ¼ in., is used to support the end of a horizontal beam. Knowing that the average normal stress in the link is -20 ksi and that the average shearing stress in each of the two pins is 12 ksi determine (a) the diameter d of the pins, (b) the average bearing stress in the link.

Two wooden members of uniform cross section are joined by the simple scarf splice shown. Knowing that the maximum allowable tensile stress in the glued splice is 63 psi, determine the largest load P that can be safely supported if W = 2.1 in, L = 10.5 in and e= 66.2. Round off the final answer to two decimal places. 012.png ... W P'

An annular washer distributes the load P applied to a steel rod to a timber support. The rod's diameter is 22 mm, and the washer's inner diameter is 25 mm, which is larger than the hole's permissible outer diameter. Knowing that the axial normal stress in the steel rod is 35 MPa and the average bearing stress between the washer and the timber must not exceed 5 MPa, examine the smallest allowed outer diameter, d, of the washer. %3D %3D +22 mm P Figure 4

Knowing that the bending moment in the reinforced concrete beam is 1100 kip?ft and that the modulus of elasticity is 3.625 *106 psi for the concrete and 29* 106 psi for the steel, determine (a) the stress in the steel, (b) the maximum stress in the concrete
