Force magnitude and direction

Analyze the operation of first, second, and third-order levers.
Explain the function of linkages, including bell cranks and push/pull mechanisms.
Describe the mechanics of rotary systems, such as CAMs and followers, simple gear trains, and pulleys and belts.
Evaluate how levers and gears transmit and transform the effects of forces.
Apply arithmetic and numerical computations, such as calculating ratios, to mechanical systems.
Use angular measures in degrees to design and analyze 2D diagrams of mechanisms.
Understand how mechanical devices function to produce specific movements by changing the magnitude and direction of applied forces.
