Suppose that you want to hold a meter stick horizontal to the ground by touching it with only two fingers. One finger is at the 10 cm mark, while the other finger is at the 20cm mark. The meter stick has a mass of 100g.

What must you do with your fingers, and what normal forces do they exert on the meter stick?

What if your fingers were at the 10cm and 12cm marks?
