A solid shaft of diameter d is subjected to twisting moment T, such that the maximum shear stress developed is τ. Now a hole of 0.5 d diameter is drilled throdghout the length of the shaft along the axis. How much torque Tmust be reduced so that shear stress remain the same?
  • a)
    T/2
  • b)
    T/4
  • c)
    T/8
  • d)
    T/16
Correct answer is option 'D'. Can you explain this answer?

Given by:

τmax = Tc/J

where c is the radius of the shaft, J is the polar moment of inertia of the shaft (πd^4/32), and τmax is the maximum shear stress.

Therefore, τmax = (16Tc)/(πd^3)

where c = d/2.

So, τmax = (16T)/(πd^3)
