Mechanisms Vocabulary
15
Friction : the resistance produced by the surfaces of two objects touching each other.
Mechanical power : the use of technology to produce energy, force, work, power, and torque.
Force : strength or power exerted on an object (pushing).
Work : force x distance
Fulcrum : the support on which a lever turns in raising or moving something.
Resistance : the property of a conductor by which it opposes the flow of an electrical current. The result is the generation of heat.
Mechanical advantage : reduces the amount of human effort necessary to exert a force and overcome a resistance. It can be determined by a formula, and it is used in rating a machine’s performance.
Resistance : weight of load x distance from fulcrum
Torque : a force that causes an object to twist along its axis.
Spur gear : a round toothed wheel. It is the simplest and most fundamental type of gear.
Gear train : a series of meshing gears used to increase or decrease the speed (RPM) of an end gear. It is also used to provide variable speeds from one drive gear.
Drive gear : the gear that produces the output energy or power.
Backlash : a gap that occurs between meshed gear teeth when the rotation of the gears first begins.
RPM : revolutions per minute. RPM is used to describe the rotations of a gear in one minute’s time.
Idler pulley : a pulley riding loosely on a shaft, used to maintain tension on a pulley belt. It accomplishes this by pressing against the belt to take up slack.
