How to find axial stresses in members AF and FN and the shearing stress in the 25 mm diameter bolt at A which is in double shear. Where a crane is made from a 100* 100 mm wood post FN and a 30 mm diameter steel rod AF as in Fiqure a. Given, maximum compressive stress of wood is 20 MPa, maximum tensile stress of steel is 240 MPa & force P is gradually increased, which of the member ( AF @ FN) will give way first. Why?
* AB= AF, BC=FN
