Determine the vertical force P which must be applied at G to maintain the equilibrium of the linkage. SOLUTION
Link ABC Assume clockwise
Then for point C xC = ( 5 ) in.
Link DEFG and for point D xD = xC = ( 5 ) in.
And for link DEFG xD = 15 5 = 15 or Then
Now = 1 3
4 G = 4 2 = 2 in. 3 yG = G cos 45
4 = 2 cos 45 3 4 = in. 3 Then, by Virtual Work. U = 0: (80 lb in.)  ( 40 lb ) xE ( in.) + P yG ( in.) = 0 10 4 80  40 + P = 0 3 3 or P = 40 lb ...
