For

the four bar linkage shown in Fig 1, the input link, OA has an

anti-clockwise angular velocity of 17 rad/s. Find the angular velocity of

link BC in rad/s when link OA makes an angle 74 degrees with the

horizontal x axis. The lengths are OA = 100 mm, AB = 260 mm, BC = 180 mm, and

OC = 180 mm.

You should determine your answer graphically. Answers should be given to

1 dp. There is a tolerance of + or – 10 % to allow for errors generated by

using the graphical method.
