Abstract
The objective of this paper is to synthesize a 5 bar planar mechanism through investigating the effect of its dimensions on its performance functions. The analysis shows that it is possible to a time ratio as large as 3, a normalized stroke as large as 1.57. The minimum transmission can be adjusted not to go below 45o and the maximum transmission angle not to exceed 135o . The paper provides synthesis monograms helping the machine designer to select the mechanism dimensions for any desired requirements (time ratio and stroke) such that the transmission angle does not violate its boundaries.

Keywords
