Engineering Mechanics - Section 1

If two bodies having masses m1 and m2 (m1>m2) have equal kinetic energies, the momentum of body having mass m1 is __________ the momentum of body having mass m2.

two like parallel forces are acting at a distance of 24 mm apart and their resultant is 20 N. It the line of action of the resultant is 6 mm from any given force, the two forces are

One watt is equal to

The force which acts along the radius of a circle and directed away from the centre of the circle is called centrifugal force.

Work done is said to be zero, when

During elastic impact, the relative velocity of the two bodies after impact is __________ the relative velocity of the two bodies before impact.

If two blocks of equal mass are attached to the two ends of a light string and one of the blocks is placed over a smooth horizontal plane while the other is hung freely after passing over a smooth pulley, then the two blocks will have some motion.

Moment of inertia of a hollow circular section, as shown in the below figure about X-axis, is
