Iron Cross Module
Objectives
- Construct a free body diagram.
- Use Newton’s Laws to mathematically analyze the free body diagram.
- Calculate torques.
- Understand equilibrium.
- Identify which muscles come into action when we perform various actions.
- Explain the difference between abductor and adductor muscles.
- Calculate muscle forces.
- Introduce muscle groups and equivalent forces.
Description
This module was written with a physics or accelerated physics class in mind and was intended to follow the Balance Module (although it could be done independently). It provides a unique and more difficult setting to learn and apply Newton’s Laws, free body diagrams, and torque.
Concepts and Skills
Physics
- Forces
- Lever arms and torques
- Equilibrium
- Newton’s third law
Biomechanics/Engineering
- Center of gravity
- Muscles as forces
- Muscle physiology
- Anthropometry
- Solve analysis problems
Math
- Work in three-dimensions
Time
This module is expected to take nine 50-minute class periods.
