Problems in Mechanics
problems” we will address in this chapter deal with
four common mechanical systems: pulleys, inclined planes, springs,
and pendulums. These systems pop up on many mechanics problems on
SAT II Physics, and it will save you time and points if you familiarize
yourself with their quirks. These systems obey the same mechanical
rules as the rest of the world, and we will only introduce one principle
(Hooke’s Law) that hasn’t been covered in the previous three chapters.
However, there are a number of problem-solving techniques that are
particular to these sorts of problems, and mastering them will help
you get through these problems quickly and easily.
