Mechanical efficiency = (output energy)/(input energy) .

It's typically stated as a percentage.

What is the mechanical efficiency of a machine that produces 400 joules of work output from work input of 500 joules?

The efficiency is 80%. To find the efficiency, 400/500 = 80%.


How do you calculate the mechanical efficiency?

Mechanical efficiency is calculated by dividing the useful work output by the total energy input, and then multiplying by 100%. The formula for mechanical efficiency is (Useful work output / Total energy input) * 100%.


What is the mechanical efficiency of a machine whose work input is 100 J and work out put is 30 J?

The mechanical efficiency can be calculated using the formula: Efficiency = (Work output / Work input) * 100%. Given the values, we have: Efficiency = (30 J / 100 J) * 100% = 30%. Therefore, the mechanical efficiency of the machine is 30%.


If a device has an ideal MA of 4 but an actual MA of 3 what is the efficiency?

Efficiency can be calculated using the formula: Efficiency (%) = (Actual Mechanical Advantage / Ideal Mechanical Advantage) × 100. In this case, the efficiency would be (3 / 4) × 100 = 75%. Therefore, the device has an efficiency of 75%.


What is a specific example of a machine and describe how its mechanical efficiency might be calculated?

An example of a machine is a car engine. Mechanical efficiency can be calculated by comparing the work output (such as the power produced by the engine) to the work input (such as the energy from the fuel). The formula for mechanical efficiency is: Efficiency = (useful work output / total work input) 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.


Is it possible to find mechanical efficiency of multi-cylinder diesel engine by Morse test?

yes


Why do you multiply to find the total mechanical advantage?

The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.
