wheel produces an oscillating motion of the lever OA. Points O and C are fixed
and the angular velocity (w) of the wheel is constant at 150 rad/s. The lengths of
the links are AB = 80 mm and OA =30 mm, the radius BC = 20 mm and distance
OC =60 mm.

ii)
Construct a vector diagram of the mechanism as shown
Calculate the following:
a) The angular velocity of the link OA and the absolute velocity of point A.
b) The radial acceleration of OA.
c) The magnitude and the direction of the acceleration of point A.
