The inversion of a mechanism is: a) Obtained by fixing different links in a kinematic chairn b) Changing of a higher pair to a lower pair C) Flipping the mechanism upside down ) Obtained b e) None of the above y reversing the input and o utput motio 7. When a slider moves on a fixed link having a curved surface, their instantaneous centre lies: a) On their point of contact b) Perpendicular to the sliding path c) At the pin joint d) Tangent to the path of the curve e) None of the above 8. The Coriolis component of acceleaions varies in direction from the sliding velocity by a) 45° b) 90° C) 135° d) 180° e) None of the above 9. Which is always true? The lines of action on a 3-force member in equilibrium must intersect at a) At a single point b) The centre of mass of the body c) At one of the edges d) At a joint e) None of the aboveExplanation / Answer
5) - Option - b
The mechanism is obtained by fixing different links of the kinematic chain by one at a time. Whatever is the number of links in a mechanism, only that much number of inversion can be obtained.
6)Option- a.
The inversion is obtained by fixing different links of the kinematic chain
7) option-e
When a slider moves on a fixed link having curved surface, their instantaneous center lies in a center of the curvature
8) option-b
the Coriolis component varies in the direction of the sliding velocity by 900
9) option - a
If three non-parallel forces act on a body in equilibrium, it is known as a three-force member. Therefore, the lines of action of all three forces acting on such a member must intersect at a common point
