The centre of gravity of a homogenous body is

the point at which the whole

A Volume of the body is assumed to be

concentrated

B Area of the surface of the body is

assumed to be concentrated

C Weight of the body is assumed to be

concentrated

D Volume and area of the body is

assumed to be concentrated

2. The first moment of area of a plane surface about

an axis situated in the plane is the product of its:

A perimeter and the distance between its

centre of gravity and the axis.

B surface area and the distance between

its centre of gravity and the axis

C

surface area and the distance between

its centre of gravity and a given side of

the plane

D

surface area and the square of the

distance between its centre of gravity

and the axis

3. A point subjected to a number of forces will be in

equilibrium, if

A Sum of resolved parts in any two

directions at right angles, are both zero

B Algebraic sum of the forces is zero

C Two resolved parts in any two

directions at right angles are equal

Algebraic sum of the moments of the

force about the point is zero
