Question

Question 1. (a) A steel tube having inner and outer dimeters of 1.5 in and 2 in., respectively, is turning at 45 rev/min. If the allowable shear stress (Tallow) of the tube material is 10 ksi, determine the horse power (hp) transmitted by the tube. (20 points) (b) The A-36 solid steel shaft is 3.5 m long and has a diameter of 60 mm. The shaft is used to transmit a torque of T-524 N-m from the engine to the generator. Determine the angle of twist (Ⓡ) of the shaft. The shear modulus of elasticity (G) of the shaft material is 75 GPa. (10 points)

Both parts please
