Question

If diameter of a shaft is doubled the power transmitted capacity
will be
alFither twice or half​

Answer 1

Answer:

1/8

Explanation:

power= 2πNT/60

T/J = shear stress/ radius

J = $\pi /4 *d^{4\\}$

T =( $\pi /4 *d^{4\\}$*F ) / (d/2)

if diameter is doubled power transmitted rduced by 1/8

Answer 2

Given,

The diameter of a shaft is doubled.

To find,

if the capacity of power transmitted will be decreased or increased

Solution,

power= 2πNT/60

T/J = shear stress/radius

J = π/(4 x d4)

T =[(π/4 xd4) *F] / (d/2)

Thus, if the diameter is doubled power transmitted is reduced by 1/8
