The foot segment shown above is subjected to the pull (F1 and F2) of the two plantar flexor muscles. Find: What is the moment of F1 about point A? (+CCW) (include units with answer) What is the moment of F2 about point A? (+CCW) (include units with answer)

Explanation / Answer

1) 26 cos 33 (4.2) + 26 sin 33 (4.9) = 160.97

2) 31 cos 72 (4.9) + 31 sin 72 (3.1) = 138.34
