The OB rod in the crank-piston mechanism shown in the figure is rotating with constant 300 revolutions per minute in counter- clockwise. The length of the OB rod is 19 cm and BA rod is 47 cm. The length of the piston is 10 cm. Find the components of the tangential (not angular) velocity and tangential (not angular) acceleration vectors (Vx, ax, Vy, ay) of the midpoint of the piston rod (BA) at the given instant by the angle 25 degrees.
