Problem 15.8 To prevent damage to floors (and to increase friction), a crutch will often have a rubber tip attached to its end. ?Part A If the end of the crutch is a circle of radius 0.85 cm without the tip, and the tip is a circle of radius 2.0 cm, by what factor does the tip reduce the pressure exerted by the crutch? Express your answer using two significant figures. $\frac{P}{P_{tip}} = $

Step 1

The area of the crutch end without the tip can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius. A = π(0.85 cm)^2 A ≈ 2.27 cm^2 Show more…
