#### How much force does it take to lift the weight?

Because there is only one load bearing section of rope, the force required to lift the weight is the same as the weight itself. The answer is 70 kg.

#### How much force does it take to lift the weight?

Because there is only one load bearing section of rope, the force required to lift the weight is the same as the weight itself.

#### What is the smallest amount of force required to lift the weight?

To determine how much force is required to lift the weight, determine how many sections of the rope are bearing the weight and divide the weight among them.

30/ 2 = 15 kg

#### What is the least amount of force required to lift the weight?

There are 2 pieces of supporting rope and when we divide the weight between them we get 120 kg.

#### What is the smallest amount of force required to lift the weight?

This pulley system appears to be more complicated than previous examples, but the same principle applies. We divide the weight among the four rope supporting sections. 800 / 4 = 200 kg

#### How much force is required to lift the weight?

Because there are two sections of rope supporting the weight, we can divide the force required to lift the weight 150/2 = 75 kg.
