GEARS AND LEVERS
Gears and levers are among the most common and illustrative simple machines. With Gears and Levers, principles such as mechanical advantage, torque, and rotating motion are easily illustrated with practical handson examples. Ratios, angles, and the geometry of the circle become “real” to your students as they deduce the rules of how the machines they build work.
Gears and Levers includes: 4 Hardwood Gears (diameters of 10, 20, and 30 cm; 12, 24, and 36 teeth), 2 Hardwood Levers, Knobs and Mounting Hardware.
