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
