The engine weighs 4500 newtons and it is lifted 1.5 meters up by the block and tackle system. The mechanic must apply a force of 225 newtons while pulling a total of 37.5 meters of chain through the block and tackle pulley system. What is the work done by the block and tackle system?
mechanic: 225N*37.5m=work done by mechanic
engine:4500*1.5 Joules work done
so, work done by block/pulley is the secondline, the work done on the engine.
To calculate the work done by the block and tackle system, we can use the formula:
Work = Force x Distance
In this case, the force applied by the mechanic is 225 newtons, and the distance the chain is pulled through the pulley system is 37.5 meters.
So, the work done by the block and tackle system can be calculated as:
Work = 225 N x 37.5 m
To get the answer, we need to multiply these two values together:
Work = 8437.5 Joules
Therefore, the work done by the block and tackle system is 8437.5 Joules.
