Solution

Q.No 1

Melbow =0:                                     

-FwRw + FmRm =0,

Where

Fm &Rm are the muscle force and its moment arm

Fw &Rw are the100N weight and its moment arm

Rw =0.3* cos 30°= 0.19 meters

-100* 0.19+ Fm * 0.03=0

Fm =633N

Q.NO 2

F _compression = W_AW/D_AW

                        = 300/0.25 = 1200

Q.No 3

F _shear = F- W_AW

         = 100
