1. The frame ABC, supported by a clamp at A and a roller at C, will be used to support a distributed load q acting vertically downward, as shown in the figure. The cross-section of the beam is rectangular with the height = 20 cm and the width = 10 cm. E=200 GPa and σy=300 MPa. q B L A L/3 C a) Determine the reaction at C if q = 20 kN/m and L=3 m. Use Castigliano's second theorem. b) Calculate the safety factor for this application according to the Tresca criterion. Neglect stresses caused by internal shear and normal forces.
