Problem 20PE

Suppose you needed to raise a 250-kg mower a distance of 6.0 cm above the ground to change a tire. If you had a 2.0-m long lever, where would you place the fulcrum if your force was limited to 300 N?

Step-by-Step Solution:

Step 1 of 3</p>

The system will be in equilibrium if the torque applied by you about the fulcrum is equal to the torque applied by the mower about the fulcrum.

From the data given, we have to calculate the distance where the fulcrum has to be placed from the applied force.

Step 2 of 3</p>

We can understand the situation from the figure below.

Let the distance of the fulcrum from you is .

Therefore, the distance of the fulcrum from the mower is m.

The torque applied by you,

…..(1)

Mass of the mower kg

Weight of the mower N

N

The torque applied by the mower,

…..(2)

Step 3 of 3
