A very practical example of mechanical advantage is the use of a "cheater bar." If you find a bolt that is hard to break, simply slip a long pipe or similar object over the handle and it will apply much more torque.

The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What is the term for the comparison of input and output work of a machine?
Sounds like you are asking about "mechanical advantage"...
If there was no friction what would that do to mechanical advantage and how would it affect efficiency?
Without friction, some forms of mechanical advantage do not function. In most cases for a mechanical apparatus, a reduction in friction is usually accompanied by an increase in efficiency.
The amount by which a machine multiplies an input force is called?
mechanical advantage
What is mechanical efficiency in science?
mechanical efficiency is the percent of the energy that you put into a machine that was transferred to the load.
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
What is the mechanical efficiency of a machine whose work input is 100j and work output is 30j?
The mechanical efficiency of this machine is 30 percent.
How do you measure efficiency?
Efficiency= Mechanical Advantage Speed ratio X100 Mechanical advantage divided by speed radio X (times) 100
The mechanical what of a machine compares the input force with the output force?
Mechanical efficiency
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
Which Mechanical efficiency has efficiency100 percent?
watches
What is used to calculate mechanical efficiency?
work
Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
What is formula for mechanical efficiency?
Mechanical efficiency:force x distance (output)/ force x distance (input) x 100%ex. 700n x 2 m / 800n x 2m x 100%1400nm/1600nm x 100%0.875 x 100%= 875Mechanical efficiency= 875%The preceding example is incorrectMechanical efficiency is: % efficiency=output power/input power x 100
