A motor provides the torque necessary to keep a gear turning at
constant angular velocity, overcoming friction between the gear and
the axle.
The gear can be modeled as a disk, with mass 2 kg, and radius
rg = 0.2 m. The force of friction can be
modeled as a single force, acting at the outer edge of the axle, at
position ra = 0.02 meters, with force of
fk = 10 N.

The average human produces about 15 g of sweat per minute during intense activities. a. If a jogger runs for 30 mins and evaporates all of the sweat he produces after his run, how much heat was transferred from his body to the sweat? Assume the jogger is always seating, the sweat’s initial temperature is 37°C, and that sweat has the same specific heat and latent heat as water. b. A heat stroke occurs when a human’s body temperature reaches...
