Question

The force F needed to loosen a bolt with a wrench varies inversely with the lenth I of the handle. Write an

Answer 1

Answer:

Step-by-step explanation:

We first need to determine what the model is for this situation. Using the inverse proportion equation, which is

$F=\frac{k}{l}$, we can find that model using the information given.

We first need to solve for k, the constant of proportionality. Using F = 250 and l = 6,

$250=\frac{k}{6}$ and

multiply both sides by 6 to get that

k = 1500

Now we use that k value along with l = 24 to solve for the force needed:

$F=\frac{1500}{24}$ so

F = 62.5 pounds
