Embibe Experts Solutions for Chapter: Rotational Mechanics, Exercise 1: SRMJEEE (UG) 2014

Torque per unit moment of inertia is equal to

The dimension of the ratio of angular momentum to linear momentum is:

A turbine fan in a jet engine has moment of inertia $2.5 \mathrm{kg} {\mathrm{m}}^2$ about its axis of rotation. Its angular velocity is $40t^2$. The net torque is

The ring of radius $1 \mathrm{m}$ and mass $15 \mathrm{kg}$ is rotating about its diameter with angular velocity of $25\mathrm{rad}/\sec$. Its kinetic energy is
