The short beam ABC is supported by a pin at C and the link BD that is pinned at B and D. All pins are in single shear and have diameters d = 15 mm. If the steel for the link and supports has an ultimate normal stress of 400 MPa and the steel in the pins has an ultimate shear stress of 240 MPa, determine the largest allowable load P on the beam for which the factor of safety is 3.0.
