My second attempt! ƩMc=ƩMA F1S1 + F2S2 =F3xS3 60 x 0.32 + 18x0.14 = F3 x 0.035 19.2 + 2.52 = 0.035 F3 22.72= 0.035 F3 21.62/0.035= F3 620.6 N = F3 I am hoping this is right!

The figure below shows a section of the human forearm in equilibrium. The weight of the object in the hand is 60 N. The centre of gravity of this object is 32 cm from the elbow. The bicep provides an upward force of magnitude F. The distance between the line of action of this force...
