A weightless rod of length `2l` carries two equal masses 'm', one tied at lower end `A` and the other at the middle of the rod at `B`. The rod can rotate in vertical plane about a fixed horizontal axis passing thriugh `C` . The rod of is released from rest in horizontal possion. The speed of the mass `B` at the instant rod become vertical is:

A weightless rod of length 2l carries two equal masses 'm' , one secured at lower end A and the other at the middle of the rod at B . The rod can rotate in vertical plane about a fixed horizontal axis passing through C . What horizontal velocity must be imparted to the mass at A so that it just completes the vertical circle.

A weightless rod of length l carries two equal masses m one fixed at the end and other in the middle ofhte rod. The rod can revolve in a vertical plane about A. Then, horizontal velocity which must be imparted to end C of rod to deflect it to horizontal position is

A weightless rod of length l carries two equal masses m one fixed at the end and other in the middle ofhte rod. The rod can revolve in a vertical plane about A. Then, horizontal velocity which must be imparted to end C of rod to deflect it to horizontal position is

A weightless rigid rod AB of length / connects two equal masses m one particle is fixed at the end B and the other at the middle ofthe rod as shown in the figure-5.131. The rod can rotate in the vertical plane freely around the hinge point/4. Choose the correct option(s)

A uniform rod of length L is free to rotate in a vertical plane about a fixed horizontal axis through B . The rod begins rotating from rest. The angular velocity omega at angle theta is given as

A uniform rod of mass m and length L is free to rotate in the vertical plane about a horizontal axis passing through its end. The rod initially in horizontal position is released. The initial angular acceleration of the rod is:

A rigid rod of mass m & length l is pivoted at one of its ends. If it is released from its horizontal position, find the speed of the centre of mass of the rod when it becomes vertical.

A rigid rod of mass m & length l is pivoted at one of its ends. If it is released from its horizontal position, find the speed of the centre of mass of the rod when it becomes vertical.

In the figure shown one end of a light spring of natural length l_(0)=sqrt(5/8)m(~~0.8m) is fixed at point D and other end is attached to the centre B of a uniform rod AF of length l_(0)//sqrt(3) and mass 10kg. The rod is free to rotate in a vertical plane about a fixed horizontal axis passing through the end A of the rod. The rod is held at rest in horizontal position and the spring is in relaxed state. It is found that, when the rod is released to move it makes an angle of 60^(@) with the horizontal when it comes to rest for the first time. Find the (a) the maximum elogation in the spring . (Approximately) (b) the spring constant. (Approximately)
