Final answer:
The top of a 20.0-m-tall hollow aluminum flagpole equivalent to a 4.00 cm diameter solid cylinder flexes due to a 900.0 N force, and the deflection is determined using beam deflection formulas and material properties.
Step-by-step explanation:
The question is asking to determine how far to the side the top of a 20.0-m-tall hollow aluminum flagpole, equivalent in stiffness to a solid cylinder with a diameter of 4.00 cm, will flex when subjected to a horizontal force of 900.0 N. Calculating this deflection requires an understanding of the material’s properties, such as the modulus of elasticity (Young's modulus) for aluminum, and the moment of inertia for the given cross-section.
Since the required material properties and the exact dimensions of the hollow flagpole are not provided, the precise calculation cannot be completed. However, in general, the calculation would involve using the formula for beam deflection under a point load, which typically depends on the force applied, the length of the beam, the modulus of elasticity of the material, and the moment of inertia of the cross-section.
