How much torque would it take to make the wheel speed up from rest to 1.5 rev/sec in 10 sec? b. Now let’s suppose that the wheel is still on the test stand and the torque is being delivered to the wheel by pulling on a chain that goes around a gear on the same axis as the wheel (it works like how the chain powers the rear wheel of a normal bicycle). The gear has a diameter of 12.5 cm. How much tension would you have to put on the chain to make the wheel speed up from rest to 1.5 rev/sec in 10 sec?
