Answer to Question #154503 in Mechanics | Relativity for NISHANT KUMAR MEENA

Question

a rod of length l varies linearly with position along its length, such that it increas to thrice its value from one end to the other. this rod is paleced on a frictionless horizontal surface and a horizontal force of magnitude f is applied to a point on the rod. at what point should this force be applied such that the rod slides on the surface without rotating

Answer 1

Answer

According to concepts of rotation there should be a couples.

But here according to above given theory couple are not given so rotational motion.

And also friction is not applied on rod.

So

If we apply force on rod at anywhere or any point such that the rod slides on the surface without rotating.
