Exact Straight line mechanisms

No matter , what industry it is , it must have straight line mechanism  in it machines . If we wanna design high complicated machines , there are most probable chances for need of straight line mechanisms.  

we can obtain straight line motion with various ways . Suppose in it , we use constraint , so that piston oscillate in straight line motion . But in this we will discuss about some mechanisms which will straight line without adding any constraint to it .

  • paucellier mechanism 
  • Hart Mechanism
  • Scott-Russel Mechanism
  • Kempe Mechanism 

These are few Exact Straight line mechanisms
