Answer:
324.3Nm
Explanation:
The torque is given by the equation
in this case the vectors r and F are perpendicular between them, thus:
The forces acting on the mass are:
(1)
where T is the tension of the cable, M is the mass and a is the acceleration.
Furthermore, we have that the acceleration is:
By replacing in (1) we can obtain:
The force T produces the torque on the pulley, hence:
the answer is 324.4Nm
hope this helps!
