A pulley system is used to lift a 2000 newton engine up a distance of 3 meters How much force will the operator have to apply if the mechanical advantage of the pulley system is 4?

A pulley system is used to lift a 2,000 newton engine up a distance of 3 meters. How much force will the operator have to apply if the mechanical advantage of the pulley system is 4? mechanical advantage = 500 newtons.


What is thermal efficiency?

Thermal efficiency is the efficiency of a heat engine measured by the ratio of the work done by it to the heat supplied to it.


Machine that transforms heat into mechanical energy?

A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine. Real engines, that obviously work at a lesser efficiency, include the combustion engines found in cars.A ficticious heat engine that works at the maximum theoretical efficiency is called a Carnot engine.

Which engine wastes the most energy?

I would say, heat engine on earth would waste the most energy since it is always limited by thermodynamic efficiency to have some loss. In general, lower the temperature difference will resulted to lower the efficiency, a simple steam engine for a train would be of lower efficiency than a internal combustion engine and lower than complex high pressure steam turbine and is probably the lowest engine efficiency in commercial scale.

How do you calculate propeller slip?

Slip=100%-Efficiency Efficiency=Observed Speed or Distance / Engine Speed or Distance Mean Apparent Slip = Distance Run by Propeller - Distance Run by Ship / Distance Run by Propeller Distance Run by Propeller = Picth X Total Engine Revolutions per day / 1852 I wish this can help those who are in need of this formula.
