Resistance (Load) Arm
Range of Motion
Coefficient of friction
- Identify tension, gravity, normal, and friction forces.
- Identify classes of levers and explain advantages and disadvantages of each in terms of mechanical advantage and range of motion.
- Apply lever and equilibrium concepts to solve for forces and find mechanical advantage in scenarios involving levers. 
- Apply normal force and friction coefficient concepts to calculate static and kinetic frictional forces.
