Gears(chapter 2)

This chapter looked deeper into the "world" of gears and went into depth of the different types of gears and also went more in depth with the different types of gear ratios there are and what types would be good for what types of things. one thing they explored were pulleys and what types of ratios are associated with pulleys and what ratios are for what type of pulleys. This chapter was also about the different types of gears are available for lego. with this chapter i get even more sense that gears are very essential things in building and moving a robot or any type of machinery really.
