## Strength of Materials Two non-collinear parallel equal forces acting in opposite direction

constitute a moment
constitute a couple
balance each other
constitute a moment of couple

joule
watt
newton
pascal

## Strength of Materials The algebraic sum of the resolved parts of a number of forces in a given direction is equal to the resolved part of their resultant in the same direction. This is as per the principle of

independence of forces
balance of force
forces
resolution of forces.

## Strength of Materials Which of the following do not have identical dimensions?

Torque and work
Moment of a force and angular momentum
Momentum and impulse
Torque and energy

## Strength of Materials The angle which an inclined plane makes with the horizontal when a body placed on it is about to move down is known as angle of

limiting friction
friction
kinematic friction
repose

## Strength of Materials Coulomb friction is the friction between

solids and liquids
two dry surfaces
two lubricated surfaces
bodies having relative motion
