Question

A solid shaft can resist a bending moment of 3.0 knm and a twisting moment of 4.0 knm together, then the maximum torque that can be applied is

a) 7.0 kNm
b) 3.5 kNm
c) 4.5 kNm
d) 5.0 kNm

Answer 1

The maximum torque that can be applied to the solid shaft is 7.0 kNm.

Step-by-step explanation:

The maximum torque that can be applied to the solid shaft can be calculated by subtracting the bending moment and the twisting moment from the maximum combined torque.

Given that the solid shaft can resist a bending moment of 3.0 kNm and a twisting moment of 4.0 kNm, the maximum combined torque is 7.0 kNm (3.0 kNm + 4.0 kNm).

Therefore, the maximum torque that can be applied to the solid shaft is 7.0 kNm.
