Homeworks-4-bar linkage-solutions Due in class on NOV.2,2011 1.A four-bar linkage has the following dimensions:480=2 in..A4=2+2 in.,B=1+ in.,BoB =2+3/4 in.(see Fig.P .1). (a)Determine the type of four-bar by the Grashof criterion. (b)Determine the range of motion of this linkage if link 2 is the input. (c)Determine the range of motion of this linkage if link 4 is the input. Ag 动 1 Figure P .1 Solution: (a)Double rocker(the link opposite the shortest is the frame (b)For link 2 as input,the range is 111.7 (c)For link 4 as input,the range is 97.6
