1. The figure on the right shows a rigid bar that is supported by a pin at A and two rods, one made of steel and the other of bronze. Neglecting the weight of the bar, 1. Find the stress in the bronze rod. 2. Calculate the axial stress in the steel rod. 2.Determine the largest weight, W, that can be supported by two wires as shown in the figure on the right. The stress in either wire is not to exceed 207 MPa. The crosssectional areas of wires AB and AC are 258

1. The rigid beam AC is supported by the 75 mm wide x 10 mm thick strut BD as shown below. If P = 3.0 kN, Determine the minimum required diameter (in mm) of the bolt at B if the allowable shearing stress is 50 MPa, 2. A hollow circular pole 300 mm in diameter, 6 mm thick, and 3 m high is fixed at the base. The pole is subjected to a torque T = 25 kN m and a lateral force H = 3 kN at the top. Modulus of rigidity G = 78 GPa and the allowable shear stress is 60 MPa. is subjected to a couple havi...
