What is the minimum effort that must be applied to lift the load?
300 / 2 = 150 kg

For every 2 metres the rope is pulled through, what height does the load rise off the ground?

1 metre

What is the mechanical advantage?

The mechanical advantage is calculated by dividing the load by the effort (load/effort). The pulley system offers a mechanical advantage of 2.

What is the maximum load that can be lifted with this system?

300 kg

For every 2 metres the rope is pulled through, what height does the load rise off the ground?

1 metre

What is the mechanical advantage?

The mechanical advantage is calculated by dividing the load by the effort (load/effort). The pulley system offers a mechanical advantage of 2

A spring balance is used to just lift a 24 kg mass, as shown on the right. What is the reading on the spring balance attached to the rope where the effort is applied?

4 kg

For every 2 metres the rope is pulled through, what height does the load rise off the ground?

2/6 = 0.3 metres

What is the mechanical advantage?

The mechanical advantage is calculated by dividing the load by the effort (load/effort). The pulley system offers a mechanical advantage of 6.
