Two pieces of steel are held together with six bolts. One end of the first piece of steel is welded to a beam and the second piece of steel is bolted to the first. There is a load of 54,000 pounds applied to the end of the second piece of steel. The tensile strength of steel is 74,000 psi, the shear strength is 48,000 psi.a) Calculate the diameter of the bolts needed to support the load.b) Find the width of the steel if the thickness of the steel is 1/4Â?. The bolt holes are 1/16Â? larger than the bolt.
