Problem 2. A 3/8 x 2-in AISI 1018 cold-drawn steel bar is cantilevered to support a static load of 250 lbf as shown below. The bar is secured to the support using two 3/8 in-16 UNC SAE grade 4 bolts. Assume the bolt threads do not extend into the joint. Find the factor of safety for the following modes of failure: shear of bolt, bearing on bolt, and bearing on the member. Properties: Bar - Sy = 54 kpsi, Bolt - Sy = 100 kpsi T L Lin in 3 in 1 in 12 in O 250 lbf
