A motor delivers 500 hp to the shaft, which is tubular and
has an outer diameter of 2 in. The shaft is rotating at
92 rad/s. 1 hp = 550 ft - lb/s. (Figure 1)
Figure

Expert Solution

Step 1

Given that,

$P o w e r d e l i v e r e d m o t o r, P = 500 h p, O u t e r d i a m t e r o f s h a f t, d_{o} = 2 i n, S p e e d o f s h a f t, ω = 92 r a d / s e c, A l l o w a b l e s h e a r s t r e s s o f s h a f t m a t e r i a l, τ_{a l l} = 25 k s i,$

Convert the unit of the power from hp to lb. ft/sec.

$P = 500 h p P = 500 [\frac{550 l b . f t / s e c}{1 h p}] P = 275000 l b . f t / s e c,$

Calculate the maximum torque by using the following equation:

$T = \frac{P}{ω} T = \frac{275000}{92} T = 2989.1304 l b . f t$
