Question

a solid steel shaft has to transmit 100kw at 150 rpm.find the shear stress if diameter is 75 mm​

Answer 1

Explanation:

Given A solid steel shaft has to transmit 100kw at 150 rpm. find the shear stress if diameter is 75 mm

• Given P = 100 kW = 100 x 10^^3 W
•         N = 150 rpm
•         D = 75 mm = 75 x 10^-3 m
• We need to find the shear stress.
•     So shear stress τ = ?
• So P = 2πNT / 60
•        Or T = 60 x P / 2π N
•                 = 60 x 100 x 10^3 / 2 x π x 150
•          Or T = 2000 / π
•           Or T = 636.9
• Now τ = 16 T / π x d^3
•            = 16 x 636.9 / π x (75 x 10^-3)^3
•           = 7.69 x 10^6 N/m^2
