11A10.40 - Muscles

Code Number:
Demo Title:
Area of Study:
Physiology, Biology
Vacuum Muscle Demo and String Ligament Demo.

Make sure the hoses on the vacuum muscle are connected tightly.  As you pull out on the hand held chamber, the muscle should contract raising the hand.

Connect the motors to a 6 V. battery.  One motor runs the upper arm and the other runs the hand muscle.  Running the motor so the string winds and becomes shorter will raise the desired part of the demo.
