CLO 1: A rigid beam rests on two bronze bars 700 mm long. Another aluminum bar is placed between them which is 699.93 mm long. If the weight of the beam is 375 KN, determine the stress in bronze bar (in MPa). Bronze Bronze Alum Alum Bronze A in mm2 850 1500 E in Gpa 70 83

The solid rod has a diameter of 20mm. Find the following: Angle of twist at C with respect to A (in radians) Angle of twist at B with respect to A (in radians) Maximum shear stress at A (in MPa) (Shear stress at support, at a point 7mm from center. (in MPa) A-36 steel with the following properties: Modulus of Elasticity, E = 29x10^3 ksi or 200 GPa Shear Modulus/Modulus of Rigidity, G = 11.5x10^3 ksi or 79.3 GPa Poisson's Ratio, nu = 0.260 Temperature Coefficient for thermal expansion, a = 6.6x10^-6/°F or 11.7x10^-6/°C
