Engineering Mechanics - Section 1 (6)

If the resultant of two equal forces has the same magnitude as either of the forces, then the angle between the two forces is

A body of weight W is required to move up on rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by(where μ = tanφ = Coefficient of friction between the plane and the body.)

The angle of inclination of a vehicle when moving along a circular path __________ upon its mass.

The range of projectile on a downward inclined plane is __________ the range on upward inclined plane for the same velocity of projection and angle of projection.

The velocity ratio in case of an inclined plane inclined at angle θ to the horizontal and weight being pulled up the inclined plane by vertical effort is

The coefficient of restitution for elastic bodies is one.

The term 'force' may be defined as an agent which produces or tends to produce, destroys or tends to destroy motion.

Two balls of equal mass and of perfectly elastic material are lying on the floor. One of the ball with velocity v is made to struck the second ball. Both the balls after impact will move with a velocity
