hii ashok....
please check the inertia explanation...
I(for the whole system) = I (rod 1) + I (rod 2) + I (rod 3)
For the rod where the rotation axis passes through the end of the rod, i'm thinking that its moment of inertia should be 1/3 ML^2.
For the rod which is parallel to the axis of rotation, monent of inertia is zero...
I(for a long thin rod with a rotation axis through it's end) = 1/3 ML^2.
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
