Hi all... I'm new here... 1. The problem statement, all variables and given/known data this is not a homework question, I'm just solving practice questions for exam preparation Two wheels with masses M1 = 2 kg and M2 = 4 kg are connected. The ratio is R1 = 5 cm and R2 = 10 cm Considering an angular velocity of ωo = 10rads-1 for the small wheel and a constant angular acceleration of α = 1 rads-2 What will be the torque τ required to stop the system after 20 s within a period of 2 s? 2. Relevant equations T1ω2=T2ω1 and P = E/t 3. The attempt at a solution I already found the energies of the Gears, E1= 1.125J and E2=2.25J but I have no idea how to find the torque needed to stop them in 2 seconds. I'm not even sure if I'm on the right track. I have like 3-4 A4 sheets worth of work all scribbled on/crossed out... actually my problem is that if I work out the Torques, their ratio comes out at 0.25 rather than 0.5, so I'm not sure what to do.
