Question

The medial deltoid attached to the humerus at an angle of 15 deg. What are the size of the rotary and stabilizing components of muscle force when the total muscle force is 500 N

Answer 1

Answer:

The size of the rotary and stabilizing components of muscle are 129.41 N and 482.96 N

Explanation:

According to the angle produced between the deltoid attached and the humerus  

The Rotary Formula (or Vertical Component) is

FR = 500 N · sin 15° = 129.41 N

and the Stabilizing Formula (or Horizontal Component) is

FS = 500 N · cos 15° = 482.96 N
