Task $2$

The mechanism below has a crank that revolves clockwise at $\backslash ($ O $\backslash ).$

Using vector diagrams, determine:

a$)$ The linear velocity of the piston and the angular velocity of the link $\backslash ($ A B $\backslash )$ about $\backslash ($ A $\backslash ).$

b$)$ The angular acceleration of the link $\backslash ($ A B $\backslash )$ about $\backslash ($ A $\backslash )$ and the inertial resistance produced by the piston.

c$)$ Using trigonometry, confirm your results for the velocity and acceleration in parts $($a$)$ and $($b$).$
