Question

A uniform rod of length l and mass m rests on supports at its ends. The right support (white triangle) is quickly removed. a) What is the force from the left support immediately thereafter? A uniform rod of length 2r and moment of inertia rests on top of two supports, each of which is a distance d away from the center where is a constant. The right support (white triangle) is quickly removed. b) What is the force from the left support immediately thereafter?

Answer 1

Answer:

Explanation:

For solving this question we will be using Newton's second law of motion in 2 different formats.

F = ma and   $\tau = I\alpha$

Here F = net external force applied on the body

m = mass of the body

a = acceleration of the centre of mass of the body

$\tau$ = net external torque on the body

I = moment of inertia of the body about given axis

$\alpha$ = angular acceleration of the body

These are 2 forms of Newton's second law of motion first one is from transnational motion and second for rotational motion.
