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.
The pulley allows the re-direction of force by 180 degrees. A ramp cannot do that. Say you need to lift an engine out of a car's engine bay. You would use a pulley because as you pull straight down the engine goes straight up. That presumes that you weigh more than the engine.
In a free pulley system, the relationship between the distance you have to pull and the force you need to apply is inversely proportional. This means that as you increase the distance you need to pull, the force required decreases. Conversely, if you decrease the distance you need to pull, the force required increases. This relationship is a result of the conservation of energy principle in a pulley system.
The mechanical advantage of the block and pulley you are using, or the engine of the fork lift truck if that is what you are using.
It is very loud like you can hear the engine from a distance.

You will need 8 drops of chain. So the operator must apply 250 newtons to the 8th drop. The other 7 drops of chain must be reeved through the pulley system.
What is the value of Wi? 7,500 joules
Yes, I am pretty sure that such pulley systems exist.

The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.
The crankshaft pulley is the large pulley on the lower passenger side of the engine.
It depends which "pulley" you mean. Drive pulleys are on the front of the engine.
It is mounted just above the crankshaft pulley on the front of the engine.It is mounted just above the crankshaft pulley on the front of the engine.
it's an alone pulley mostly found bulted to engine block. the belt can run under or over it
In an Inline 6 Jeep engine, the idler pulley is located to the right of the A/C pulley. It is a smooth pulley, not a grooved one.
Look on your car's engine.
