A system of pulleys is used to lift a 100 kg load. If there are multiple pulleys with strings and the system has mechanical advantage, calculate the tension in the string and the force required to lift the load.

The tension in the string can be calculated using the formula:
Tension = Load * Mechanical Advantage
The mechanical advantage of a pulley system is equal to the number of ropes supporting the load. Let's say there are n ropes.
In this case, there are multiple pulleys with strings, so we need to know how many ropes are supporting the load. Let's say there are m ropes.
The mechanical advantage is then given by:
Mechanical Advantage = m
Using the given information, we know that the load is 100 kg.
The tension in the string is then calculated as:
Tension = 100 kg * m
Now, let's calculate the force required to lift the load.
The force required to lift the load is equal to the tension in the string. Therefore, the force required is also:
Force = 100 kg * m
This means that the force required to lift the 100 kg load is equal to the tension in the string, which is 100 kg times the mechanical advantage of the system.
