(See attached file for full problem description)
A four car linkage is shown in the attachment. The crank OA, the connecting rod AB, and the rocker BC are 20mm, 120mm, and 60mm long respectively. The crank rotates at a speed of 60 rpm and the centre distance OC is 90mm. At the instant shown determine:
(I) The velocity of C
(II) The angular velocity of the rocker BC
(III) The angular velocity of the connecting rod AB
The solution calculates the angular velocity for various parts of a car including the crank, the connecting rod, and the rocker.
