The velocity of the belt for maximum power is (where m = Mass of the belt in kg per meter length)

The secondary unbalanced force due to inertia of reciprocating parts in a reciprocating engine is given by (where m = Mass of reciprocating parts, ω = Angular speed of crank, r = Radius of crank, θ = Angle of inclination of crank with the line of stroke, and n = Ratio of the length of connecting rod to radius of crank)

The flank of the tooth is the surface of the tooth __________ the pitch surface.

When the two elements of a pair have __________ when in motion, it is said to a lower pair.

When a shaking force is transmitted through the springs, damping becomes detrimental when the ratio of its frequency to the natural frequency is greater than

The relation between number of pairs (p) forming a kinematic chain and the number of links (l) is
