The beam, which is assumed to be rigid, is on top of three short columns. Edge columns are made of brass, and the middle column is made of aluminum. Brass and aluminum materials are assumed to be ideal elastoplastic. Yield stresses are (Obr)A = 560 MPa and (Cat)A = 20 MPa, elasticity modules are Ebr = 100 GPa and Eal = 70 GPa. The edge dimensions of short square columns are apr = 20 mm, dal = 50 mm. Neglect the weight of the rigid beam. a) Write the equilibrium equation and compatibility condition. b) Find the P = PA force as soon as aluminum starts to yield. (kN) c) Calculate the failure load PG. (kN) P. SOLUTION aluminium rigid beam brass brass KL-*> LKL
