Iron Cross Module

Objectives

  1. Construct a free body diagram.
  2. Use Newton’s Laws to mathematically analyze the free body diagram.
  3. Calculate torques.
  4. Understand equilibrium.
  5. Identify which muscles come into action when we perform various actions.
  6. Explain the difference between abductor and adductor muscles.
  7. Calculate muscle forces.
  8. 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.

Physics
Biomechanics/Engineering
Math

Time

This module is expected to take nine 50-minute class periods.
