A thin uniform rod of length l and mass m rotates uniformly with angular velocity w in the horizontal plane passing through one of its ends. The tension in the rod as a function of x as rotational motion is
Explanation:
Taking a small mass of dm at the distance x
The centrifugal force acting on this mass
Again
Mass per unit length
Thus mass of length dx
Thus
Tension in the mass dm
Tension in the whole rod
Hope this helps.
