Chapter 5, Problem 5/144 The disk rolls without slipping on the horizontal surface. If the disk has a clockwise angular velocity of wo-21 rad/s and a counterclockwise angular acceleration of 3.6 rad/s2 determine the veloclty and acceleratlon of pln A relatlve to the slotted member BC and the angular velocity and angular acceleratlon of BC. The value of r is 225 mm. Neglect the distance from the center of pin A to the edge of the disk. The relative velocity...

An green hoop with mass mh = 2.8 kg and radius Rh = 0.17 m hangs from a string that goes over a blue solid disk pulley with mass md = 2.4 kg and radius Rd = 0.08 m. The other end of the string is attached to a massless axel through the center of an orange sphere on a flat horizontal surface that rolls without slipping and has mass ms = 3.4 kg and radius Rs= 0.19 m. The...

A hoop of mass M = 3 kg and radius R = 0.4 m rolls without slipping down a hill, as shown in the figure. The lack of slipping means that when the center of mass of the hoop has speed v, the tangential speed of the hoop relative to the center of mass is also equal to vCM, since in that case the instantaneous speed is zero for the part of the hoop that is in contact with the...
