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

On 45° latitude
On equator
On the poles
On 30° latitude

3/5
5/3
3/4
4/5

## Applied Mechanics and Graphic Statics The time period of a simple pendulum depends on (i) Mass of suspended particle (ii) Length of the pendulum (iii) Acceleration due to gravity

All are correct
Both (i) and (iii)
Only (i)
Both (ii) and (iii)

## Applied Mechanics and Graphic Statics The forces which meet at one point and have their lines of action in different planes are called

Non-coplanar non-current forces
Intersecting forces
Coplanar non-concurrent forces
Non-coplanar concurrent forces

## Applied Mechanics and Graphic Statics Coefficient of friction depends on

Area of contact only
Both (A) and (B)
Nature of surfaces only
None of these
