In the below picture shown is a variation of Scotch Yoke Mechanism, where length of the crank is R, and angle between sliding block and plunger/vertical axis is beta.
In the below pictures, described how to derive equation to find displacement of the plunger (x) in terms of crank length R, crank angle theta and sliding block angle alpha.
To find the velocity of plunger (V), differentiate displacement equation (x) with respect to time once and to find acceleration of the plunger (a), differentiate displacement equation (x) twice, the procedure and final equations for velocity and acceleration of the plunger are shown in the below picture.
