Hi, here in this given problem, suppose this straight line represents the outstretched arm of the person and here this is the palm of the person carrying a load in it.
00:22
This is the center of the load.
00:25
This point is the shoulder.
00:31
So we mark it as s.
00:39
Here this is the elbow joint and we mark it as e.
00:47
This point is the wrist joint.
00:53
We mark it as w and weight of this load in vertically downward direction, angle of the arm with the horizontal.
01:07
That is given as 24 .0 degree.
01:13
Weight w, that is 22 .5 newton length of the arm between shoulder and elbow, that is 29 .5 centimeter between elbow and wrist joint.
01:36
This is 22 .0 centimeter.
01:40
And from wrist joint to the center of palm that is just 6 .0 centimeter...
