The inversion of a mechanism is
-
The coefficient of fluctuation of energy is the ratio of maximum energy to the minimum energy.
-
When the nature of contact between the elements of a pair is such that it can only slide relative to the other, the pair is known as a
-
The velocity of a particle moving with simple harmonic motion, at any instant is given by (where ω = Displacement of the particle from mean position)
-
The velocity of piston in a reciprocating steam engine is given by (where ω = Angular velocity of crank, r = Radius of crank pin circle, θ = Angle turned by crank from inner dead centre, and n = Ratio of length of connecting rod to the radius of crank)
-
The primary unbalanced force is maximum __________ in one revolution of the crank.
-
The instantaneous centres which vary with the configuration of mechanism, are called
-
The displacement of the reciprocating roller follower, when it has contact with the straight flanks of the tangent cam, is given by (where r1 = Minimum radius of the cam, r2 = Radius of the roller follower, and θ = Angle turned by the cam from the beginning of the follower displacement)
