Answer 2

The torque transmitted by a solid shaft of diameter 40mm if the shear stress is not to exceed 4MP a would be​

To determine the torque that can be transmitted by a solid shaft of diameter 40mm with a maximum shear stress of 4 MPa, we need to use the formula for torsional stress:

τ = T / J

where:
τ = shear stress (MPa)
T = torque (Nm)
J = polar moment of inertia (mm^4)

The polar moment of inertia can be calculated as:

J = (π/32) * d^4

where d is the diameter of the shaft.

Substituting the values, we get:

J = (π/32) * (40mm)^4 = 31,415 mm^4

And using the formula for torsional stress, we can solve for T:

T = τ * J = 4 MPa * 31,415 mm^4 = 126,460 Nm

So, the maximum torque that can be transmitted by a solid shaft of diameter 40mm with a maximum shear stress of 4 MPa would be 126,460 Nm.
