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%= 875
Mechanical efficiency= 875%
The preceding example is incorrect
Mechanical efficiency is: % efficiency=output power/input power x 100

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 would happen to a pulley system if the load were increased?
Ideal mechanical advantage is the mechanical advantage when there is no friction. It is the mechanical advantage when the efficiency of the pullefy system is 100%. It is a constant for that system of pulleys. Therfore it is not affected by increasing or decreasing the load. But actual mechanical advantage will be less than this ideal mechanical advantage due to friction. In other words the efficiency will be less than 100 %. If the efficiency is 80%, it implies 20% is wasted due to friction while lifting a load. If we increase the load the friction also increases and hence the efficiency will decrease with the load.
The more efficient a machine is the closer the actual mechanical advantage is to the?
Perfect efficiency
Why a normal machine could not have the mechanical efficiency of 100?
Because there is always going to be friction, the efficiency of any machine will always be less then 100 percent.
How do you calculate power if flowpressure and efficiency is given?
formula are given at www.calculatoredge.com
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
What is the formula for calculating efficiency of a mechabical system?
Assuming you meant mechanical, Energy output / Input x 100
What is formula for thermal efficiency?
Thermal Eff = (mechanical heat produced/electrical heat produced) x 100%
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.
How do you calculate effort the machine of velocity ratio 5 and efficiency 60 percent calculate the effort required to lift a load of 300N?
efficiency=mechanical advantage/velocity ratio mechanical advantage=load/effort use this formula, ans:100N

The mechanical efficiency of this machine is 30 percent.
What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
