22) The method of obtaining different mechanisms by fixing in turn different links in a kinematic chain, is known as
Answer is:
Inversion
Related Theory of Machines MCQ with Answers
Answer is:
All of the above
Explanation:
Following are the difference between a machine and a structure
* The parts of a machine more relative to one another, whereas the members of a structure do not move relative to one another
* The links of a machine may transmit both power and motion, whereas the members of a structure transmit forces only
* A machine transforms the available energy into some useful work, whereas in a structure no energy is transformed into useful work
Answer is:
Obtained by fixing different links in a kinematics chain
Answer is:
Each of the four pairs is turning pair
Explanation:
Four bar chain or Quadric cycle chain consists of four links, each of them forms a turning pair. The inversions of four bar chain are as follows.
* Beam Engine (Crank and lever mechanism)
* Coupling rod of a locomotive (Double crank mechanism)
* Watt's indicator mechanism (Double lever mechanism)
