I have been asked this question in my homework.

Origin of the question is Acceleration of a Point on a Link topic in section Acceleration in Mechanisms of Machine Kinematics

Answer 1

The correct answer is (c) A-3,B-4,C-1,D-2

Explanation: Law of correct steering    – cotɸ – cotɸ = c/b

 Displacement relation of Hook’e joint   – tanϴ = tanɸ cosα

 Relation between kinematic pairs and links – f = 3(n – 1) – 2j

 Displacement equation of reciprocating engine piston – x = R[ (1 – cosϴ) + sin^2ϴ/2n].
