Question

In a isometric exercise a person places a hand on a scale& pushes vertically downward, keeping the forearm horizontal.This is possible because the triceps muscle applies upward force Mperpendicular to the arm, as the drawing indicates. The forearmweighs W forearm = 22 N & has a center of gravity as indicated.The scale registers FN= 111N. Determine the magnitude ofM. Thanks. Must see the book diagram.

Explanation / Answer

   as from the given thenet torque about anaxis through the elbow joint will be     = (111 N) (0.300 m) - (22.0 N)(0.150 m) - (0.0250 m) M          = 0    solve for M    M = ........ N
