Question

find the magnitude of the force that the elbow joint exerts on the forearm.

Answer 1

231. cos 44 + y compoent of the force = 132.5
y compoent of the force = -39.17 N

x compoent of the force= 231. sin 44 = 160 .46

Resultant = √ [ 39.17 ^2 ^2 + 160 .46^2] =165.17 N

Angle = arc tan 39.17 /160 .46

13.71°
