A uniform plant of Young's modulus Y is moved over a smooth horizontal surface by a constant horizontal force F. The area of cross section of the plank is A. The compressive strain on the plank in the direction of the force is

A rod of length L kept on a smooth horizontal surface is pulled along its length by a force F. The area of cross-section is A and Young's modulus is Y. The extension in the rod is

A plank of mass m_1 with a uniform sphere of mass m_2 placed on it rests on a smooth horizontal plane. A constant horizontal force F is applied to the plank. With what acceleration will the plank and the centre of the sphere move provided there is no sliding between the plank and the sphere?

A plank of mass M is placed on a rough horizontal surface and a contant horizontal force F is applied on it . A man of mass m runs on the plank find the range of acceleration of the man that the plank does not move on the surface is mu .Assume that the does not slip on the plank

A uniform sphere is placed on a smooth horizontal surface and a horizontal force F is applied on it at a distance h above the surface. The acceleration of the centre :

A uniform sphere is place on a smooth horizontal surface and as horizontal force F is appied on it at a distance h above the surface. The acceleratioin of the centre

A uniform elastic rod of cross section area A natural length L and Young's modulus Y is placed on a smooth horizontal surface. Now two horizontal forces (of magnitude F and 3F) directed along the length of rod and in opposite direction act at two of its ends as shown . After the rod has acquired steady state, the extension of the rod will be

A sphere of mass m and radius r is placed on a rough plank of mass M . The system is placed on a smooth horizontal surface. A constant force F is applied on the plank such that the sphere rolls purely on the plank. Find the acceleration of the sphere.

A plank of mass m_(1) with a sphere of mass m_(2) on it rests on a smooth horizontal surface. A canstant horizontal force F is applied to the plank. With what sliding between the plank and the sphere? [hint: Rel vel. Of the lowest point v-(2) + epsilonR -v_(1) =0 for no sliding)

A uniform elastic plank moves due to a constant force F_(0) applied at one end whose area is S . The Young's modulus of the plank is Y . The strain produced in the direction of force is
