Detailed Solution for Test: Theory of Machines Level - 2 - Question 14

There are six degree of freedon three translation and three rotational and constarint motion is refered when pair of machine element are move or rotate in a required motion with unnessesary motion are restricted thats type of motion are called constrained motion in above example foot step bearing and rotor only 2 degree of freedom 1 rotation cw and acw and 1 translation up and down but translation dof are restricted by gravity self wait of rotor so that type of constrain motion are called succesfully constrained motion.
