## Applied Mechanics and Graphic Statics The force acting on a point on the surface of a rigid body may be considered to act

On any point on the line of action of the force
At the centre of gravity of the body
At any point on the surface normal to the line of action of the force
On the periphery of the body

(i) and (iv)
(ii) and (iii)
(i) and (iii)
(ii) and (iv)

## Applied Mechanics and Graphic Statics If a body is lying on a plane whose inclination with the horizontal is less than the angle of friction, then i. a force is required to move the body upwards ii. a force is required to move the body downward iii. the body will not be in equilibrium The correct answer is

only (i)
only (ii)
both (i) and (iii)
both (i) and (ii)

## Applied Mechanics and Graphic Statics The torque produced by a force depends on i. the magnitude of the force ii. the direction of the force iii. the point of application of the force relative to origin The correct answer is

both (i) and (ii)
both (i) and (iii)
all (i), (ii) and (iii)
only (i)

None of these
