Understanding Tension and Normal Reaction

Normal and Tension

What is normal reaction ?

Understanding Phase OF SHM

Examples on Torque||Shifting OF Normal Reaction||Toppling.

A uniform rod of mass m and length l is in equilibrium under the action of constraint forces, gravity and tension in the string. Find the a. frictional force acting on the rod. b. tension in the string. c. normal reaction on the rod. Now, the string is cut. Find the d. angular acceleratiion of the rod just after the string is cut. e. normal reaction on the rod just after the string is cut.

What do you mean by normal reaction?

The angle made by the resultant of normal reaction and limiting value of frictional force with normal to the surface is called ?
