E
  • Engineering Notebook:
    A type of journal that the students will use to record their designs, ideas, and reflections as they move through the STEM Lab.
G
  • Gear:
    A method of mechanical power transmission. There are many different types of gears, and they are found very commonly in the world.
  • Gear Ratio:
    Is the relationship between the numbers of teeth on two meshing gears used to transmit motion. It reflects the change in mechanical advantage resulting from the gears.
M
  • Mechanical Advantage:
    Is the calculation of how much faster and easier a machine makes your work. It compares the output force a mechanism or machine gives you to the input force that is applied to that mechanism or machine to get it to work.
S
  • Speed:
    A measure of how fast an object is moving. It describes a change in position with time, or more simply put, how far an object will travel over a given period of time. This measure is given in units of distance per time, such as miles per hour or feet per second.
T
  • Torque:
    A spinning force. Torque is described by the magnitude of the force multiplied by the distance it is from the center of rotation. Torque is measured in units of force times distance, such as inch-pounds or newton-meters.
  • Transmission:
    The transference of force between machines or mechanisms, often with changes of torque and speed.
V
  • V5 Gear Box:
    A machine built with VEX V5 hardware that uses compound gear ratios to create a mechanical advantage of 125:1.
