An elastomeric bearing pad is used to support a bridge girder as shown. The bearing pad provides flexibility in the horizontal direction to accommodate thermal expansion and earthquake motions. The shear modulus of the bearing pad is G = 1.50 MPa. The beam must not displace horizontally more than 25 mm when a load of P = 45 kN is applied as shown. Determine the maximum thickness t that can be used for the bearing pad. Assume a = 300 mm and b = 420 mm. b

A hollow box beam is constructed with webs of Douglas-fir plywood and flanges of pine, as shown in the figure in a cross-sectional view. The plywood is 1 in. thick and 12 in. wide; the flanges are 2 in. × 4 in. (nominal size). The modulus of elasticity for the plywood is 1,800,000 psi and for the pine is 1,400,000 psi. If the allowable stresses are 2000 psi for the plywood and 1750 psi for the pine, find the allowable bending moment Mmaxwhen the beam is bent about the z axis. Repeat part (a) if the beam is now bent about its y-axis.
A steel bar has a square cross section of width b = 2.0 in. (sec figure). The bar has pinned supports at the ends and is 3.0 ft long.
