A string is wrapped around a uniform disk of mass M = 2.1 kg and radius R = 0.12 m. (Recall that the moment of inertia of a uniform disk is (1/2) MR².) Attached to the disk are four low-mass rods of radius b = 0.16 m, each with a small mass m = 0.7 kg at the end. The device is initially at rest on a nearly frictionless surface. Then you pull the string with a constant force F = 30 N. At the instant when the center of the disk has moved a distance d = 0.041 m, a length w = 0.033 m of string has unwound off the disk. •m bi m m Part 1 M, R Part 2 d V= 0.708548386 Your answer is correct.

In an under-construction building, an elevator lift has to be installed to ease the movement of engineers, workers, etc. from the ground floor to the top floor. The elevator lift is of mass 2.95 tons including passengers (workers and engineers) and has to be raised with an acceleration of 55 m/s using a hoist drum of 1.9 m diameter. The drum's mass is 810 kg and the radius of gyration is 465 mm. The effect of bearing friction is equivalent to a couple of 2.8 kN-m at the host drum. A motor has to be selected based on torque requirement and you (working as an Engineer at a construction site) have been asked by your supervisor to carry out the following tasks. Determine the Value of Moment of Inertia I kg-m2 Determine the Value of Effort in the rope to lift the elevator E= N-m Determine the Value of Torque T=
