9-46. The press consists of two rigid heads that are held together by the two A36 steel 12-mm-diameter rods. A 6061-T6-solid-aluminum cylinder is placed in the press and the screw is adjusted so that it just presses up against the cylinder. Determine the angle through which the screw can be turned before the rods or the specimen begin to yield. The single-threaded screw on the bolt has a lead of 0.25 mm. Note: The lead represents the distance the screw advances akıng its axis for one complete turn of the screw. -300 mm - so mm -250

The Am1004-T61 magnesium tube is bonded to the A-36 steel rod. A torque of 7.5 kN⋅m is applied to end A. A) Determine the maximum shear stress in magnesium. Express your answer to three significant figures and include the appropriate units. B) Determine the maximum shear stress in steel. Express your answer to three significant figures and include the appropriate units. C) Determine the shear stress on the inside surface of the magnesium tube. Express your answer to three significant figures and include the appropriate units.

The 10-mm-diameter bolt is made of an aluminum alloy. It fits through a magnesium sleeve that has an inner diameter of 15 mm and an outer diameter of 25 mm. The original lengths of the bolt and sleeve are 80 mm and 50 mm, respectively. If after the nut on the bolt is tightened the tension in the bolt is 10 kN, determine the change in dimension of the cross-section of the bolt and the sleeve. Assume the material at A is rigid. E = 70 GPa, Emg = 45 GPa, Ga = 26 GPa, Gmg = 17 GPa.
