What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
Why it is not possible to attain 100 percent efficiency in lever?
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
What is the mechanical advantage formula for a 1st class lever?
fd=MA
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
What is the maximum efficiency any machine can have?
Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."
What is the formula of efficiency?
The formula of efficiency is power output divided by the power input.
If the work put into a lever is 930 joules and the work accomplished is 870 joules the efficiency of the lever is?
94%
What is the formula for calculating efficiency?
General formula for calculating efficiency is given by Efficiency = (output / input) * 100 It is denoted by greek letter Eta Efficiency cannot be more than 100%.
Why efficiency is greater then 1 in case of compound lever?
why efficency is greater than 1 in case of compound lever
What is the formula to efficiency?
Efficiency = (output power/input power) x 100%
What is the formula for calculating cooling efficiency?
How to calculating cooling efficiency of air cooler
Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
What is the formula for efficiency?
Output/Input * 100= %
How do you find the input power in the electric efficiency formula if you have the output power and the efficiency percent?
Output equals efficiency times input; in formula, Ot = Ef x In and so In = Ot/Ef. To calculate the original input, divide the output by the efficiency.
Can you achieve 100 percent efficency with a lever and fulcrum?
Not if you consider the energy expended to grip or engage the lever--this does account for a minimum amount of lost efficiency
What is the formula for finding weight at simple lever?
a lever has a mechanical advantage of 5 . how heavy an object can the lever move if a person exerts 100N force on the lever?
Why it is not possible to attain 100 percent efficiency in lever?
Some of the force used in a lever will be to overcome friction, this means that not 100% of the force can be used to lever as some of it will be used to overcome friction as well as an multitude of other forces.
