Hi
I have a few questions that I have from observing some everyday phenomenon:
1) I was wondering, when one hits a brake on the car, why does the car lean forward and compress the front brake?
2) If I have a plastic rotorblade (like on propeller) and I apply a force perpendicular to the plane of the blades (like if I push the blade with my hand), does the amount of deflection change if the blade was rotating at different speeds?
3) My bike's brake is acting strange; when I flip the bike upside down (so wheel not touching the ground) and rotate the peddle as fast as I can and brake, the wheels stop instantaneously, but if I ride the bike (on flat plane), the brakes basically do not work (I basically feel like I'm traveling at a slower, but constant velocity), I was wondering why this is?
Thanks
