Problem 1: A structure is made of a horizontal beam AF and a weightless inclined bar CD with pinned connections at A, C and D. The structure is designed to lift a crane that carries 10 kN. The tapered beam is 25 mm thick and its height varies linearly between 150 mm at end A to 250 mm at end F. Member AF's specific weight is 80 kN/m³. 3m Determine the required diameter for the pin at connection A if the allowable shear stress capacity is 350 MPa. What is the required thickness of each of the two plates at connection A if the allowable bearing stress capacity is Ob= 200 MPa. A E B -2m-2m-2m- F 1 m 10 kN Connection A
