Chapter 5, Problem 34PE
A 20.0-m tall hollow aluminum flagpole is equivalent in stiffness to a solid cylinder 4.00 cm in diameter. A strong wind bends the pole much as a horizontal force of 900 N exerted at the top would. How far to the side does the top of the pole flex?

A 20.0 m tall hollow aluminum flagpole is equivalent in strength to a solid cylinder of aluminum 3.50 cm in diameter. A strong wind bends the pole much as a horizontal force of 900 N exerted at the top would. How far to the side (in mm) does the top of the pole flex?
A 20.0-m-tall hollow aluminum flagpole is equivalent in strength to a solid cylinder 4.00 cm in diameter. A strong wind bends the pole as much as a horizontal 900.0-N force on the top would do. How far to the side does the top of the pole flex?
Watch your units and choose Young's modulus wisely.

Hint
During a wrestling match, a 157.0 kg wrestler briefly stands
on one hand during a maneuver designed to perplex his
already moribund adversary. By how much does the upper
arm bone shorten in length? The bone can be represented
by a uniform rod 39.5 cm in length and 2.1 cm in radius.
