nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.
The transmission lever is very simple and there is no friction.
In machines, this is always the case, since the machine won't work at 100% efficiency.
Not if the laws of physics - specifically thermodynamics - are correct.
Yes, 200 percent is greater than 28 percent.
1 percent is less than 25 percent. 1 percent is greater than 0.25 percent.
ideal machines have mechanical efficeincy equal to 1 (100% efficient) since efficiency is the ratio of the power output to the power input
No, 3.075% is not greater than 3.125%.
66.2 percent is greater than 35 percent.
0.2 percent is greater than 0.05 percent.
0.03 percent is greater than 0.02 percent.
You don't. Such an efficiency can be less than 1, but it can't be greater than 1.
