A non uniform rod AB has a mass M and length 2L the mas per unit length of the rod is mx at a point of the rod distant x from A.find the moment of inertia of this rod about an axis perpendicular to the rod (!)through A (2)through the mid point of ABAns) consider a strip of the rod ''dx'' at a length ''x'' from A.mass of the small strip is mx*dx.moment of inertia of the small strip about A IS m*x*dx*x*x.on integrating we get moment of inetia about A as 4*m*L*L*L*L.ABOUT MID POINT OF AB.consider a strip of length ''dx'' at a distance of x from mid point P.mass of it is m*(L-x)*dx.moment of inertia of half of the rod about P is m*(L-x)*dx*x*x.on integration we get moment of inertia of half of the rod.similarly do for the other half.adding them we get the answer.
A data transmission rate; the maximum amount of information (bits/second) that can be transmitted along a channel is called band width.

KINEMATICS II 1. The concept of the derivative of the function is exceptionally important. The derivative shows that how fast the function changes when its argument is changed.
Regard as two charged particles. At a given separation each one particle exerts a force of 12 N on the other. What force does every one exert on the other after someone moves the p
The average speed of a substance in a given interval of time is explained as the ratio of the distance done to the time taken whereas; average velocity is explained as the ratio of
What is Modern view Modern view : It objects tend to remain in their initial state; force is needed to change motion. Resistance to alters in motion is known as inertia.
