1. why are tapered roller bearings and angular contact bearings really common for fsae unsprung systems? is this something that could be transferrable to solar cars?
   1. is it important for us to be able to withstand thrust and radial loads at the same time? 
   2. how does this change bearing calculations?
2. step down? (ie. having a larger outer-board bearing but a smaller inner-board bearing) This could save space and save weight, but how does this affect loads?
   1. having one bearing?
3. designing fixtures/figuring out tolerances for specific bearings? how should bearings be retained?
4. how important is surface contact consideration/materials?
   1. bearings prevent metal/metal contact, reducing friction, heat, and wear. 
5. What is the best wag to reduce rolling resistance?
   1. what is bearing hysteresis?
      1. philip explanation: hysteresis is the reason a bearing doesn't spin foreve, internal forces within bearing that are non-linear 
6. calculating dynamic loads?
   1. at some point, we should draw a free body diagram of the hub, sum forces & moments and solve for bearing reaction forces
