    (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

    Problem:

    A four-bar linkage is shown below. The crank OA, the connecting rod AB and the bar 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:

    1) The velocity of B
    2) The angular velocity of BC
    3) The angular velocity of the connecting rod AB.

    Solution:

    Remark: in the original text of problem, first question refers to point C, but it cannot be like that, because C is fix (like point O) and the ...

    Solution Summary

    The solution calculates the angular velocity for various parts of a car including the crank, the connecting rod, and the rocker.
