The following is the inversion of slider crank chain mechanism
A quarternary joint is equivalent to
The frequency of oscillation at moon compared to earth will be
The total number of instantaneous centres for a mechanism for n links is
The number of pairs of links or the number of instantaneous centres is the number of combinations of n links taken two at a time. Mathematically, number of instantaneous centres, N = n(n – 1)/2
According to Kennedy's theorem, if three bodes have plane motions, their instantaneous centres lie on
The direction of Corioli's component of acceleration is the direction
The magnitude of the Corioli's component of acceleration of a slider moving at velocity V on a link rotating at angular speedw is
Cam size depends upon
In the scotch yoke mechanism, Corioli's component is
The brake commonly used on train boggies is
