4. Figure shows an unbalanced fourbar linkage. 30 R-33, Link 2 a=2 M my-10g my-82 g ma-48 g R =? Link 3 m ms B-179 60 27 23 50 Link 4 Balance this linkage using two balancing weights of m = m = 100gm. Please note, all dimensions are in mm, unless stated otherwise. The distance and angular orientation of the second balancing weight mg, relative to link 4 has been determined for you. There values are shown in figure. Determine the distance R and angular orientation of the first balancing weight m, relative to link 2.
