An electric motor has a rotor with a mass moment of inertia of 21 ft-lb-s2. What torque is required to accelerate it from rest to 1,167 rpm in 7.5 seconds? Provide your answer in lb-ft and round to the nearest whole number. Crate A is moved 17 ft to the right by the forces shown in the figure. Force y is 84 lb and force z is 49 lb. Force z is 13 degrees below horizontal. Determine the work done. A y lb 77 4 3 Bº zlb An electric motor has a rotor with a mass moment of inertia of 21 ft-lb-s2.
