Merry Muscles
If you have a bicycle with 3 gears on the back wheel, why is it easier to peddle in some gears than others?
(Hint: remember that to change a moment of inertia the distribution of the masses has to change and also think about what provides a torque on the back wheel)? Which gear is the easiest to peddle in (larges middle or smallest)?
2) If you want to push a merry-go-round and make it as easy as possible, where should you tell your friends to sit?
3) Explain why your arm works and why your muscles (not your arm itself) are amazing. (Hint: think about where the muscle attaches.
1) You never get something for nothing. Little pedal gears and big wheel gears let you go fast, but you need to push harder. Big pedal gears and little wheel gears make you not need to push so hard, but you don’t go so fast.
2) Moment of inertia I = MR^2. So move your friends to the middle to minimize I.
3) Your muscles contract. They hook on to your armbones above the joints, so by contracting, they cause the bones to rotate about the joints.
