Lecture notes on Basics of Kinematics

Here we have just the basic definitions and the formulae used to solve few problems of standard form

General table to solve problems related to centroid and moment of inertia

Lecture notes related to Moment of Inertia or Second moment of areas of a LAMINA.....

Derivations related to some standard Lamina

Lecture notes related to Centroid of LAMINA.....

The centroid is centre of mass of a two-dimensional planar lamina or a three-dimensional solid. The mass of a lamina with surface density function  is

(1)

and the coordinates of the centroid (also called the centre of gravity) are

			(2)
			(3)

The centroid of a lamina is the point on which it would balance when placed on a needle. The centroid of a solid is the point on which the solid would "balance."

Dear Student friends after having a look at the above definition and equation you may get a view that it would be very difficult to find centroid of a lamina, but its really simple..... go through the post and revert with your comments.....
