I wrote it..We are just given Length of rod (L)in numbers which is 1.8 m..And i wrote already that ¥(angular velocity)=12V/7L..We have to calculate V in nos..
Shahid0072 said:Tim..Torque is variable..We know change in angular momentum ..What can we do?
Shahid0072 said:I guess u haven't read my earliear post..Torque varies as Mgx cos§ where x is insect's distance from centre and § is angle rotated by rod..Initial moment of inertia of rod +insect is 7MLL/12 AND when rod is vertical is MLL/3..How to calculate V in numbers?
Shahid0072 said:Oh..Pardon..Its 7MLL/48
¥(angular velocity)=12V/7L
