1. What quantities should you know to calculate or determine the moment of Inertia of an object?

2.         What is torque and what effect does torque has on an objects motion?

Homework Answers

Answer #1

1 ans

mass and radius of object are the quantities to determined the moment of inertia of an object

the moment of inertia I=mr^2

where m=mass of object

        r= radius of object

2 ans

torque :-

the rate of change of angular momentum is directly propertional to the resultant external torque acting on it and takes place in the direction of the torque

T=dL/dt (or) F*r

the effect of the torque is to change the direction of motion of object

Question: Should we calculate the moment of inertia of the rectangular bar by assuming it is a long thin rod rather than a bar with a discernible width? In other words, which geometry will yield a lower error value and explain why it will? And If the hollow cylinder was twice as heavy but its inner and outer radii were unchanged, how would its moment of inertia ge affected? Explain why.
