- What is the maximum power that can be delivered by a hollow propeller shaft (outside diameter 50 mm, inside diameter 40 mm, and shear modulus of elasticity 80 GPa) turning at 600 rpm if the allowable shear stress is 100 MPa and the allowable rate of twist is 3.0°/m?A propeller shaft for a small yacht is made of a solid steel bar 104 mm in diameter. The allowable stress in shear is 48 MPa, and the allowable rate of twist is 2.0° in 3.5 meters. (a) Assuming that the shear modulus of elasticity is G = 80 GPa, determine the maximum torque that can be applied to the shaft. (b) Repeat part (a) if the shaft is now hollow with an inner diameter of 5d18. Compare values to corresponding values from part (a).A tubular shaft being designed for use on a construction site must transmit 120 kW at 1,75 Hz, The inside diameter of the shaft is to be one-half of the outside diameter. If the allowable shear stress in the shaft is 45 MPa, what is the minimum required outside diameter d?
- A 1.5-inch Monel shaft is used in a torsional application. Based on the operating speed of 100 rpm and factor of safety of 12. How much horsepower can it transmit? Assume the shearing stress is ¾ of the ultimate tensile stress which is 100 ksi.Determine the minimum diameter that can be used for a solid circular steel shaft which is limited to an allowable shear stress of 70 MPa and a maximum angle of twist of 1.5o (degrees) per meter length. Applied maximum torque is 25 KN-m and the overall shaft length is 1.25 meters. Shear modulus = G= 80 GPa Note: When using torsion stress formulas, you must convert the angle of twist from degrees to radians.A motor driving a solid circular steel shaftwith diameter d = 1.5 in. transmits 50 hp to a gear atB. The allowable shear stress in the steel is 6000 psi.Calculate the required speed of rotation (number ofrevolutions per minute) so that the shear stress in theshaft does not exceed the allowable limit.
- A compound shaft consists of two segments. Segment (1) is a solid bronze [G = 45 GPa] shaft with an outside diameter of 80 mm, a length L1 = 780 mm, and allowable shear stress of 65 MPa. Segment (2) is a solid aluminum alloy [G = 26 GPa ksi] shaft with an outside diameter of 95 mm, a length L2 = 620 mm, and allowable shear stress of 40 MPa. The maximum rotation angle at the free end of the compound shaft must be limited to φA ≤ 2.5°. Determine the magnitude of the largest torque TA that may be applied at A.The figure shows an inboard engine, 8-ft long steel drive shaft, and propeller for a motor boat.
