. A solid circular shaft has to transmit a power 6 MW at 1400 rpm without exceeding the shearing stress of 70 Mpa and angle of twist of 1 degree in a length of 26 times the diameter. How much should be the diameter of this shaft if the modulus of elasticity of shaft material is 90 Mpa and Poisson's ratio is 0.26. Assume that the material remains elastic.

a) An internal combustion engine of 100 horsepower (hp) transmits power to the car wheels of an automobile at 600 rev/min (rpm). Neglecting any transmission losses, determine the minimum permissible diameter of the solid circular section steel shaft if the maximum shear stress in the shaft is limited to 75MPa. What will be the resulting angle of twist of the shaft, due to the applied torque, over a length of 1 m? Given that the rigidity modulus, G = 50...

A steel shaft transmits 20 kW of power at 10 Hz. Determine the smallest safe diameter of the shaft if the shear stress τmax is not to exceed 50 MPa and the angle of twist θ is limited to 5°in a length of 4 m. Use G = 70 GPa. Using the relationship θ = TL / IpG in the above problem, again determine the diameter that is necessary to satisfy the requirement of rigidity (remembering to convert θ from...
