Solution

To solve the problem, we need to apply some knowledge from physics related to force and the properties of materials, particularly focusing on the relationship between force, radius, and stress.

1. Break Down the Problem

Let's denote:

  • F F = original force
  • r r = original radius
  • 40r 40r = new radius (40 times the original radius)

The relationship in question likely pertains to some physical law, such as those governing structural forces or pressure, depending on the context implied (though it isn't explicitly stated). If the force scales with the area (as it often does in contexts of pressure), we need to consider how the area changes with the radius.

2. Relevant Concepts

The area A A of a circle can be calculated using the formula: A=πr2 A = \pi r^2

When the radius is increased to 40r 40r , the new area A A' becomes: A=π(40r)2=π×1600r2=1600πr2 A' = \pi (40r)^2 = \pi \times 1600r^2 = 1600 \pi r^2

3. Analysis and Detail

The original area A A is: A=πr2 A = \pi r^2 Therefore, the ratio of the new area to the original area is: AA=1600πr2πr2=1600 \frac{A'}{A} = \frac{1600 \pi r^2}{\pi r^2} = 1600

Assuming that the force is evenly distributed across this area and increases proportionally with area (as in the context of hydraulic systems or similar), the new force F F' can be represented as: F=1600F F' = 1600F

4. Verify and Summarize

Thus, the new force when the radius is increased to 40 40 times its original length is 1600 1600 times the original force.

Final Answer

The new force is 1600 1600 x original force.
