The rigid block of mass M is supported by the three symmetrically placed rods. The ends of the rods were level before the block was attached. Determine the largest allowable value of M if the properties of the rods are as listed (w is the working stress): Copper 160 mm Steel M Copper Steel 240 mm Copper 160 mm -1.0 m-1.0 m E (GPa) 120 200 A (mm²) 900 1200 Gw (MPa) 70 140 The rigid block of mass M is supported by the three symmetrically placed rods.
