Question

Kindly answer the and explain the questions given below

Part B: Moving a Bicycle Wheel Equipment • rotating platform with stool . bicycle wheel Procedure 3. Have a different group member sit on the stool. Have another group member rotate the bicycle wheel as quickly as possible. Orient this rotating wheel so that it is rotating cow in a horizontal plane when viewed from above and pass lit to the stationary person on the stool. Observe what happens when the person stops the wheel's rotation with their hand. Note the direction of the perso rotation (CW CCW) and the magnitude of their angular velocity relative to that of the wheel initially. 4. Have a different group member sit on the stool. Have another group member rotate the bicycle wheel as quickly as possible. Orient this rotating wheel so that it is rotating in a vertical plane and pass it to the stationary person on the stool. Observe what occurs to the person's rotation a) when they flip the wheel horizontally so that it is rotating ccw when viewed from above, b) when they flip the wheel horizontally so that it is rotating cw when viewed from above, and c) when they return the wheel to

Answer 1

2 Suit Initially the person and stool system Hence, the angular morrentun and torque applied in was at vest- mant stool system was zero. s texternal = Sł system =O At t stool makes a But as the wheel is spinning it has certain angular manenteum and a net torque. → When bicycle wheel is given to a person; wheeltperson system but due to spinning wheel it has some angular marentum. Now ow if you fap the whad Such that its motion is ccw center clockle) in the horizontal plane. In order to flop the wheel you have applied torque an it. To canyeure the angular momentum wheel will

an Eapplied on person on wheel Tobbelieve also apply equal and opposite toque on you such that the met torque system will still remain gew. anwheel + Zapplied by wheel = 0 by pessonanstool -Zapplied by wheel by person in stool person Using Right hand thank ruk; the direction of angular momentum (when wheel is morning cow) is upwards. Que to torque applied by wheat, pesson on stool will more in clockuise direction so that the angular momenten of (stoolt man) System is downwards. So, the net angular morentum of system will still be canseved iss Zero, (a) stool motion clockwise wheel rotales in if bicycle (cw, cw directa (b) if motion of bicycle whead is changed to then person would mae in opposite direction iej cow direction and retums to earlier place (if torque applied in both cases is game). scow wheel cow Sotle CW offee (9)

,کاC Procedure 3: when the person sitting on stool sites on stops the wheel then angular momentum is transferred to that persona Wheel stops but bersen on stool starts rotating. (In this case momentum is transferring to direction of rotation of wheel and stool will se same). - wheel cow if you stop it, stool moves cow. If wheel is and you stopit with hand, stool also moves Procedure 4: vertically spinning when is gires to person on stool and he flips it in hargantal plane by applying a fosque, the wheet would apply equal and opposite would cause more in opposite toque direction - if wheels is in cew stod mores in cw. wheel is in Cw stool moves in cew. Cw. hen him to man that if (To conserve the angular momentum of system). - If the person returns the wheel nothing will the happen, he will remain at dest.
