Question

Amanda uses a wheel barrel to lift a load of bricks. The bricks weigh 600 N which is more than Amanda could normally carry. However with the wheelbarrow amanda can lift the bricks with as little as 120 N what is the mechanical advantage of the wheelbarrow

Answer 1

[AI-generated answer — Bot GPT 3.5]

The mechanical advantage of a machine is defined as the ratio of the output force to the input force.

In this case, the output force is the weight of the bricks (600 N) and the input force is the force Amanda needs to apply to lift the bricks (120 N). Therefore, the mechanical advantage of the wheelbarrow is:

Mechanical Advantage = Output Force / Input Force
Mechanical Advantage = 600 N / 120 N
Mechanical Advantage = 5

Therefore, the mechanical advantage of the wheelbarrow is 5.
