Question: In the four-bar linkage shown in Fig 2.1, link 2 is to rotate completely and link 4 oscillate through an angle of 75 degrees. Link

In the four-bar linkage shown in Fig 2.1, link 2 is to rotate completely and link 4 oscillate through an angle of 75 degrees. Link 4 is to be 114 mm long; and when it is at one extreme position, the distance O2B is to be 102 mm and at the other extreme position is 229 mm. Determine the length of links 2 and 3, and draw the mechanism to scale as a check. Determine the maximum and minimum transmission angles.
