Answer:
Explanation:
It is given that,
Mass of bundle of shingles, m = 10 kg
Upward acceleration of the shingles,
The radius of the motor of the pulley, r = 0.17 m
Let T is the tension acting on the shingles when it is lifted up. It can be calculated as :
T = 113 N
Let is the minimum torque that the motor must be able to provide. It is given by :
So, the minimum value of torque is 19.21 N-m. Hence, this is the required solution.
