A hollow shaft made of red-brass copper (G = 37 GPa, shear yield strength = 150 MPa) is sandwiched between two solid shafts made of the same material. End A is fixed to a rigid wall and torques are applied to the shaft as shown. 75 kNm d₂160 kNm A d₁ L₁ B Use the following values in your working out: L₂ L₁ = 1.5 m L3 = 2.2 m d₁ = 1 m d₂ = 0.7 m d3 = 1.2 m C d₂ 3 L3 130 kNm D a) Draw a torque diagram for the entire shaft. b) Determine the maximum allowable inner diameter for the hollow section of the shaft, to the nearest mm. c) Determine the maximum length of L₂ (to the nearest mm) that will ensure the angle of twist of D relative to the wall is less than 2°. Use your value from part b for the inner diameter of the hollow shaft. d) By estimating relevant load(s), dimensions, and material properties, calculate the approximate angle of twist between two (non-coincident) points on the object shown below. Clearly state all assumptions, including the location of the chosen points.
A so-called "trapeze bar" in a hospital room provides a means for patients to exercise while in bed (see figure). The bar is 2.3 m long and has a cross section in the shape of a regular octagon. The design load is 1.4 kN applied at the midpoint of the bar, and the allowable bending stress is 180 MPa. Determine the minimum height h of the bar. Round to one decimal place. (Assume that the ends of the bar are simply supported and that the weight of the bar is negligible.) hmin mm

NEED ANSWER ASAP!! A so-called "trapeze bar" in a hospital room provides a means for patients to exercise while in bed (see figure). The bar is 2.1m long and has a cross section in the shape of a regular octagon. The design load is 1.6kN applied at the midpoint of the bar, and the allowable bending stress is 240 MPa. Determine the minimum height h of the bar. Round to one decimal place. (Assume that the ends of the bar are simply supported and that the weight of the bar is negligible.) hmin=___mm

1) The head H is connected to the cylinder of a compressor using six steel bolts. If the clamping force in each bolt is 4000N, determine the normal strain in the bolts. Each bolt has a diameter of 5 mm. If o₂ = 280 MPa and Est = 210GPa, what is the strain in each bolt when the nut is unscrewed so that the clamping force is released? a) 0.970 b) 0.203 c) 0.970(10-³) d) Insufficient information to determine because the stress is beyond yield point H &
