In-class question

Two wheels with fixed hubs, each having a mass of 1 kg, start from rest, and forces are applied as shown. Assume the hubs and spokes are massless, so that the rotational inertia

is I = mR2 . In order to impart identical

angular accelerations, how large must F be?

BLUE: 0.25 N

YELLOW: 0.5 N

PINK: 1 N

PURPLE: 2 N

GREEN: 4 N
