An elastomeric bearing (G=130 psi) is used to support a bridge girder as shown to provide flexibility during earthquakes. The beam must not displace more than 38 in. when a 5-kip lateral load is applied as shown. Knowing that the maximum allowable shearing stress is 60 psi, determine (a) the smallest allowable dimension b, (b) the smallest required thickness a.
1. The member BD is attached to a rod at B, to a hydraulic cylinder at C, and to a fixed
support at D. The bolt used at D acts in double shear and is made from a steel for
which the maximum allowable shearing stress is Tallow = 40 ksi. The rod AB is made
of a steel for which the maximum allowable tensile stress is Oallow = 60 ksi. The
upward hydraulic force applied at C is 12 kip.
1) Calculate the minimum diameter of the rod AB.
2) Calculate the minimum diameter of the bolt at D.
