Homework
Lab: Beam breaking (Ex. 6.8). There has been some interesting work on fracture of spaghetti noodles published in scientific journals lately.
Extras: High winds level forests. Here is a relevant 2016 article by French physicists about the critical wind speed at which trees break. They cite the work of Galileo. Also: here is a nice modern discussion of how living organisms' anatomy varies with their size. This approach is largely derived from Galileo's discussion of scaling in his Dialogues.

- Automobile problem: A 1500 kg automobile has a wheel base (distance between wheels) of 3 meters. The center of mass of the automobile is on at the center line at a point 1.2 meters behind the front axle. Find the force exerted by the ground on each wheel.
