About This Product
Many working models need a steady turning input, and this hand wheel unit lets the teacher supply it by hand, for driving dynamos, line shafts, flywheels, pumps and similar apparatus. Because the 20 mm intermediate pulley is much smaller than the 75 mm driving pulley, the output turns faster than the hand wheel, giving a step-up ratio of 3.75. The unit measures 16 x 16 cm. School Educational Instrument can ship the Hand Wheel Driving Unit For Physics Lab to Zambia, the United States, Saint Lucia, Mexico and Kiribati.
