The dynamic friction is the friction experienced by a body, when the body

In under damped vibrating system, the amplitude of vibration

When the axes of the shafts, over which the gears are mounted, move relative to a fixed axis, then the train is known as reverted gear train.

The two elements of a pair are said to form a __________ when they permit relative motion between them.

The centre distance between two meshing involute gears is equal to

When the two elements of a pair have a surface contact when relative motion takes place and the surface of one element slides over the surface of the other, the pair formed is known as a

In railway axle boxes, the bearing used is

A disturbing mass m1 attached to the rotating shaft may be balanced by a single mass m₂ attached in the same plane of rotation as that of m₁, such that (where r₁ and r₂ are the radii of rotation of m₁ and m₂ respectively)
