Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.

Can any pulley have a efficiency over 100?
No. A perfectly frictionless machine could have an efficiency of 100%. Anything less perfect must have can efficiency less than 100%.
How do you calculate the capacity of a machine using formula?
how to calculate the embroidery machine capacity and Embroidery factory capacity and efficiency.
What is the Maximum efficiency machine?
The electric space heater. It's the only common machine that's 100% efficient.
What is the mechanical efficiency of a machine that produce 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
How do you increase a Thermal efficiency of brayton cycle?
by increasing the turbine inlet gas temperature
Why is it difficult to increase the efficiency of a machine?
cheese
How is the efficiency of a compound machine calculated?
The efficiency of a machine is found by dividing the amount of work done by a machine by the amount of energy used by a machine. The answer is then multiplied by 100 to give a percentage.
How do ball bearings increase the efficiency of many machines?
they reduse the friction between the machine parts.
What cannot be done by a simple machine?
Increase Work
Does a machine with an efficiency of 1.2 requires a smaller effort force than a machine that has an efficiency of 2.2?
Efficiency is a measure of power losses. A machine with an efficiency of say 85% or 0.85, experiences 15% power losses from input to output (as heat through friction) This would be typical for say a car, comparing crankshaft power to power at the drive wheels. No machine will exceed 100% efficiency > Work done = force * distance Efficiency = work done at output / work done at input > Mechanical Advantage (leverage) is distance moved by input / distance moved by output. Output force = input force * Mechanical Advantage
What is percent efficiency?
it is the amount of work that can be done. a machine can use 300,000 J of energy but it only uses 263,000 J. that is percent efficiency.
Formula to calculate work efficiency?
efficiency formula is (Wout/Win)*100% Wout is the work done by the machine is called the output work Win is the work done by you on a machine is called the input work efficiency= useful work output/work input For science, the effiency is: AMA/IMA * 100
43. Which cannot be done by a machine?
D) increase velocity
What machine compares the output work onth input work?
Thats machine efficiency, you need to measure force and distance (work done) at each end and install in : % efficiency = (work out / work in) * 100
Why is a high efficiency machine is more desirable than a low efficiency machine?
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
What can you do to increase the efficiency of a machine?
Reduce losses from friction so forth in transmission of power. Ensure fuel utilized to the fullest.
The efficiency of a machine is usually expressed in?
The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.
