Figure-5.139 shows three identical kiting spools at rest on a rough horizontal groundinitially.In each case the string is pulled in the direction shown in figure. In each case it is given that spool rolls without slipping. In what direction will each spoolwill move and with what acceleration. Moment ofinertia ofeach spool is 7and radius of innertube is r and that ofouter disc is R.

In figure mass m_(1) slides without friction on the horizontal surface, the frictionless pulley is in the form of a cylinder of mass M and radius R , and a string turns the pulley without slipping. Find the acceleration of each mass, and tension in each part of the string.

A disc of mass m and radius R lies flat on a smooth horizontal table. A mass less string runs halfway around it as shown in figure. One end of the string is attached to a small body of mass m and the other end is being pulled with a force F. The circumference of the disc is sufficiently rough so that the string does not slip over it. Find acceleration of the small body.

The spool shown in the figure is placed on a rough horizontal surface and has inner radius r and outer radius R . The angle theta between the applied force and the horizontal can be varied. The critical angle theta for which the spool does not roll and remains stationary is given by

A spool of thread of mass m is placed on an inclined smooth plane set at an angle theta to the horizontal. The free end of the thread is attached to the wall as shown in figure-5.74. Calculate the acceleration of the centre of mass of the spool , if its moment of inertia about its axis is Iand the radius of the wound thread layer is r. [("g sin" theta)/(1 + (I)/(mr^(2)))]
