Lever pulley fulcrum - Study guides, Class notes & Summaries

Classes of Levers - Answer Class 1, Class 2, Class 3 Class 1 Levers - Answer Fulcrum is in the middle, with the effort (input) force on one side of the fulcrum and resistance (output) on the other side .Mechanical Advantage greater or less than 1 Ex: Seesaw, Crowbar, Pair of Scissors. Class 2 Levers - Answer Resistance is in the middle, the effort is applied on one side of the resistance and the fulcrum on the other side .Mechanical Advantage is always greater than 1 Ex: Wheelbarro...

lever - A rigid bar that is free to move around a fixed point Pulley - A simple machine that consists of a rope that fits into a groove in a wheel fulcrum - fixed point on a lever effort force - the force you exert on a lever load - the mass of an object that is moved or lifted by a machine work - when you exert a force on an object that causes the object to move some distance in the direction of the force. Joules - unit for work inclined plane - A ramp or slope that reduces the force ne...

Which pulleys provide mechanical advantage? - Answer movable Formula for gear revolutions - Answer r(revolutions) x d (number of teeth) = R x D Pulley mechanical advantage - Answer number of parts of the rope that act on the load Note about mechanical advantage: - Answer mechanical advantage is gained by combining a fixed pulley with a moveable pulley or another fixed pulley of a different diameter What are hydrometers? - Answer They use floats to measure specific gravity ...
