A mechanical device requires 420 j of work to do 230 j of work in lifting a crate what is the efficiency of the device?
The efficiency is (output energy)/(input energy) = 340/400 = 85%
What is the efficiency percentage of a mechanical device which requires 430 J of work to do 230 J of work in lifting a crate?
230/430 = 53.49% (rounded)
How do you know when you have crossed the threshold of a mechanical device?
how do you when you have crossed a threshold for a mechanical device
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 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 definition of thermal efficiency of gas engine?
In general, efficiency is the ratio between the output of a device and the input, . For thermal efficiency, the input, , to the device is heat, or the heat-content of a fuel that is consumed. The desired output is mechanical work, , or heat, , or possibly both.From the first law of thermodynamics, the energy output can't exceed the input, so

230/430 = 53.49% (rounded)
Why the efficiency of induction motor is less than that of transformer?
Because, the losses of IM is more due to the contribution of friction losses at shaft bearings and wind age losses in rotor air gap, this reduces the efficiency of the equipment, Since transforms is a static equipment zero mechanical loss so efficiency of the equipments in high .
What is the formula to find mechanical efficiency?
Mechanical efficiency = (output energy)/(input energy) . It's typically stated as a percentage.
