Question

The AB loop is given at an radius R with center O. Knowing that R = 12 cm and AB = 12 cm, determine the smaller cavities of AB, the larger cavities of AB, the distance of the O point from the AB loop and the triangle of OAB.

Answer 1

Step-by-step explanation:

when force F is applied , Cylinder tends to move in anticlockwise Hence , direction of force of friction f f f at Points A l B are as Shown .
