•Cord
•Force sensor
2
Steps
1- Clamp the arm model horizontally.
2- Lock the shoulder at zero
3- Attach cord . Adjust the length of the of the cord so that the elbow
is held at about 90o
4- Connect force sensors to your interface.
5- add deferent mass at The palm of the hand.

7- Prepare a graph to plot biceps force versus load.
8- Start data collection
9- Hook the second force sensor onto the model’s hand and pull it downward.
Slowly increase the force while watching the graph.
