Theory of machines - Section 1 (5)

If ω/ω_n = 2, where co is the frequency of excitation and ω_n is the natural frequency of vibrations, then the transmissibility of vibration will the

The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the clockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O)

In vibration isolation system, the transmissibility will be equal to unity, for all values of damping factor, if ω/ω_n is

The acceleration of the particle moving with simple harmonic motion is inversely proportional to the displacement of the particle from the mean position.

The primary unbalanced force is maximum when the angle of inclination of the crank with the line of stroke is

The Whitworth quick return motion mechanism is formed in a slider crank chain when the

When the connection between the two elements is such that only required kind of relative motion occurs, it is known as self-closed pair.

The pair is known as a higher pair, when the relative motion between the elements of a pair is
