How much effort force would you have to use to lift a 800 newton load using a pulley system with a mechanical advantage of 4?
1/4 of the load
To calculate the effort force required to lift the load using a pulley system with a mechanical advantage of 4, you can use the formula for mechanical advantage:
Mechanical Advantage = Load Force / Effort Force
Rearranging the formula, we have:
Effort Force = Load Force / Mechanical Advantage
Given that the load force is 800 Newtons and the mechanical advantage is 4, we can substitute these values into the formula:
Effort Force = 800 N / 4 = 200 N
Therefore, to lift the 800 Newton load using a pulley system with a mechanical advantage of 4, you would need to apply an effort force of 200 Newtons.
