    16. Gear Terminology

    17. Spur Gear Terminology

    18. Spur Gear - Tooth Parts

    19. Gear Tooth Size Called Diametral Pitch

    20. Purpose of a Gear Energy Transmission In the proper combination can be used to increase or decrease speed and torque

    21. Gear Rotations

    22. Determining Gear Rpm

    23. What Is Torque? The turning effort (measured in inch-pounds or foot-pounds) that causes something to rotate. When torque produces rotation, then work is done.

    24. Determining Torque

    25. Importance Modern Multi Speed Bicycles

    26. Also

    27. Car 3 Speed Transmission

    28. Gear Facts The rpm of the larger gear is always slower than the rpm of the smaller gear. Mating gears always turn in the opposite direction. Gears locked together on the same shaft will always turn in the same direction and at the same rpm. Mating gears always have the same size teeth (diametral pitch). The gear ratio between mating gears is the ratio between the number of teeth, the pitch diameters and the rpms.

    29. Gear Review What is a gear? Name 4 different types of gears. What is torque and rpm? What is diametral pitch & how is it shown? List 10 places where gears are used.
