3. For the given structure and boundary conditions, what is the allowable load Pallow if the material strengths in shear and tension are t = 200 MPa and o=360 MPa, respectively? The pins carry shear and bars BC and DE carry axial load. Disregard the stress conditions of member ACD, which carries lateral load. All pins are in single-shear and have a diameter of 12mm. Use a factor of safety of 2.0. A ABC = 100mm2 B D C Pallow E ADE = 100mm2 240mm 150mm
