A bead of mass m is fitted on to a rod and can move on it without friction. At the initial moment the bead is in the middle of the rod. The rod moves translationally in a horizontal plane with an acceleration a in a direction forming an angle `alpha` with the rod. Find the acceleration of the bead relative to the rod.

A

g sin `alpha`

B

`(g + a_(0)) sin alpha`

C

`g sin alpha + a_(0) cos alpha`

D

`g sin alpha - a_(0) cos alpha`

Text Solution

Verified by Experts

The correct Answer is:
D

mg sin `alpha` - m`a_(0) "cos" alpha = ma`

A rod touches a disc kept on a smooth horizontal plane. If the rod moves with an acceleration a , the disc rolls on the rod without acceleration a , the disc rools on therod without slidding. Then , the acceleration of the disc w.r.t the rod is

A rod of mass 'm and length L is attached to a L shaped plank at 'A'. rod can move freely about A. A string is tied between rod and plank as shown in figure. Whole system is moving with a constant acceleration g in x-direction If string is cut at any instant then the angular acceleration of rod (with respect to the plank) at that instant is

In the arrangement shown in fig., mass of the rod M exceeds the mass m of the ball. The ball has an opening permitting it to slide along the thread with some friction. The mass of the pulley and the friction in its axle are negligible. At the initial moment, the ball was located opposite the lower end of the rod. When set free, both bodies began moving with constant accelerations. Find the friction force between the ball and the thread if t seconds after the beginning of motion, the ball got opposite to the upper end of the rod. The rod length equals l.
