TA 0.5 m A Go A cord is wrapped around a homogeneous disk of mass 15 kg. The cord is pulled upwards with a force T= 180 N. Determine: (a) the acceleration of the center of the disk, (b) the angular acceleration of the disk, and (c) the acceleration of the cord.

Figure below shows a system of pulley and two loads connected through two cables. The two loads have the same mass. The weight of the cylinder is equal to the combined weight of the loads (Wc=2W1). The system is released from rest. (a) Determine the magnitude and direction of the angular acceleration of the pulley, (b) Which cable will experience more tension, cable 1 or cable 2? Why? NOTE: The mass moment of inertia of a cylinder with a radius of R and a mass of m is determined using ½.m.R². L Pulley 1. ft 0.6 ft 1 L

A drum can rotate about a fixed-point O. The A block is attached to a cord wrapping around the drum. The mass of the drum is md = 100kg and the radius is r = 0.5 m. The radius of gyration of the drum about point O is ko=0.3 m. The mass of the block is mb= 20kg. The block is released from rest. The acceleration due to gravity is g=9.81 m/s2.   (1) Calculate the mass moment of inertia of the drum about the point O, IO_______(kgm2) (two decimal places)
