The centre of gravity of a coupler link in a four bar chain mechanism will experience.
For a four-bar linkage in toggle position, the value of mechanical advantage is:
Which of the following refers to the collection of particles, whose relative distances are constant?
It is required to connect two parallel shafts, the distance between whose axes are small and variable. They can be coupled by
When the kinematic pairs are coupled in such a way that the last link is joined to the first link to transmit definite motion and completely or successfully constrain motion, it is called a -
When the relative motion between two elements is completely or successfully constrained, then these two elements form a-
