Final answer:
The problem is a physics question requiring the calculation of how far a 20-meter tall aluminum flagpole flexes to the side when a 900 N horizontal force is applied to the top.
Step-by-step explanation:
The question pertains to the bending of a hollow aluminum flagpole when subjected to a strong wind or an equivalent horizontal force. Specifically, a 20.0-m-tall flagpole, which has the same stiffness as a solid cylinder with a diameter of 4.00 cm, experiences a horizontal force of 900 N at the top. The problem is to calculate how far the top of the pole flexes to the side as a result of this force.
