What is the equation for Mechanical Advantage?
MA=resistance distance/effort distance
MA=effort force/resistance force
MA=resistance force/effort force
MA= effort distance/resistance distance
What is effort (input) force?
the force one exerts on a machine
the force which an effort force must overcome in order to do work on an object via a simple machine.
the force the machine exerts on a object
the output work times the input distance
What is resistance (output) force?
the force required by a machine in order to accomplish work (the force you put on the machine)
The force that is exerted by a machine
the force the machine exerts on a object
the output work times the input distance
Lamar Gant, U.S. powerlifting star, became the first man to deadlift five times his own body weight in 1985. Deadlifting involves raising a loaded barbell from the floor to the level of the hips with outstretched arms. Determine the work done by Lamar in deadlifting 300 kg to a height of 0.90 m above the ground (W=Fd).
