What I learned today: The type of pin/support that attaches one figure to another dictates the type of normal force that originates from that area. A pin support has both x and y componants of the normal force whereas a roller only has a normal force perpendicular to the ground.
Other Notes: The photo is of my purse legs and shoes while sitting at my desk in class. You can also see my friends shoe, who always dresses up in full desert storm fatigues for class everyday.
I had a hard time focusing today because I was feeling a little dehydrated. I really must drink more water, especially when I am feeling ill.
