Using Gear Ratios with the V5 Motor – STEM Library
Increase Speed (high speed) - With this type of gear ratio the objective is to increase the speed from the motor, such as from a motor to a wheel. The driving gear has more teeth than the driven gear. For example, if a motor drives a 60T gear to a driven 12T gear on a wheel, when the 60T driving gear rotates once, the 12T driven gear rotates five (5) times.اقرأ أكثر
Human Body Ratios | STEM Activity
The head-to-body ratio is a little more complex as it changes from a ratio of about 1 to 4 for a small child to about 1 to 8 for an adult. A five-year-old is likely to have a head-to-body ratio of about 1 to 6. It is good to remember that these ratios are averages over a large group of people. Individual variations will occur.اقرأ أكثر
