Theory of Machines MCQ with Answers

276) Kinematic pairs are those which have

Answer is:

two elements that permit relative motion

Explanation:

The two links or elements of a machine, when in contact with each other, are said to form a pair. If the relative motion between them is completely or successfully constrained (i.e. in a definite direction), the pair is known as kinematic pair.

277) If the opposite links of a four bar linkage are equal, the links will always form a

Answer is:

parallelogram

278) Higher pairs are those which have

Answer is:

point or line contact between the two elements when in motion
