Formula for calculating efficiency of a mechanical system?
Efficiency % = (Output/Input) x 100
Why 100 percent heat not convert in mechanical work in engine?
No engine is 100% efficient: there is always some loss of energy between input and output.
When were the mechanical devices built?
Mechanical devices have been built since ancient times, with significant examples dating back to around 300 BC. Notable inventions include the Antikythera mechanism from ancient Greece, which was created around 150-100 BC, and various water clocks and simple machines like levers and pulleys. The development of more complex mechanical devices continued through the Middle Ages and the Renaissance, culminating in innovations such as clockwork mechanisms in the 14th century and later advancements during the Industrial Revolution in the 18th and 19th centuries.
How does hydraulic pressure create a mechanical advantage in a simple hydraulic jack?
to understand this answer we have to assume the following as givin fact. fluids do not compress, that out of the way, the hydraulic piston you push is a smaller diameter than the piston that does the work. for example lets say that you are using a 1 square inch piston as the one you are pressing, and you are using a 100 square inch piston as the one doing work. these numbers are greatly exaggerated but will work for the example if you put 10 pounds of pressure on the 1 inch cylinder, you will have 10 psi of pressure. when this is routed to the 100 square inch cylinder you will still have 10 psi of pressure, but now it is acting on 100 square inches (10 pounds per square inch times 100 square inches) this would calculate to 1000 pounds. it would be the same as a 1001 inch lever with the fulcrum being 1 inch in from one end, only you would exert force on the larger lever to gain a mechanical advantage. hydraulics used in this way are known as liquid levers
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 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 if the input is 1000 and the output work is 600?
The mechanical efficiency is calculated by dividing the output work by the input work and multiplying by 100%. In this case, the mechanical efficiency is (600/1000) * 100% = 60%.
