Mechanical Engineering MCQ for Engineering Mechanics

This is the Mechanical Engineering MCQ for Engineering Mechanics engineering questions & answers for various interviews, competitive examination and entrance test.

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 mechanical advantage of a lifting machine is the ratio of

 
 
 
 

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

 
 
 
 

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

 
 
 
 

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

 
 

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

 
 
 
 

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

 
 

According to principle of conservation of energy, the total momentum of a system of masses in any direction remains constant unless acted upon by an external force in that direction.
