Question #118396

A solid shaft of 10cm diameter transmits 74 kW at 150 rev/min. Calculate (a) the

torque on the shaft, (b) the maximum shear stress developed, (c) the angle of twist in a

length of 1.50m, and (d) the shear stress at a radius of 3cm. Take G = 8 MN/cm2

torque on the shaft, (b) the maximum shear stress developed, (c) the angle of twist in a

length of 1.50m, and (d) the shear stress at a radius of 3cm. Take G = 8 MN/cm2

Expert's answer

a)

"T=4711\\ Nm"

b)

"\\tau=24\\cdot10^6\\frac{N}{m^2}"

c)

"\\frac{4711}{ \\frac{\\pi}{32} (0.1)^4}=\\frac{8\\cdot 10^{10}\\theta }{1.5}"

"\\theta=0.00899735\\ rad=0.5155\\degree"

d)

"\\tau'=2.76\\cdot10^7\\frac{N}{m^2}"
