This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...

Now I get to do something with that force scale I built. I had a request some time ago to talk about friction. Friction is surprisingly complicated. When two surfaces rub against each other, why is ...
