An industrial overhead door has a chain and sprocket system designed to reduce the force needed by an operator to open and close the door. the system consists of two individual systems that are connected through a live axle shaft. to operate the door, the operator pulls a continuous loop of chain over a fixed 22 tooth sprocket that is attached to a live axle shaft. the second 22 tooth sprocket is attached to a drum that drives the door. what is the overall system ratio?

(2) (a) you have a simple circuit that consists of only a battery (δvbat=1.5v) and two resistors with resistance r1=10ω and r2=5ω, connected in series with each other. what is the current running through the battery? (b) you re-arrange your circuit so now r2 is attached in parallel to r1 rather than in series. what is the current running through the battery? (c) you add an additional resistor r3=7ω on the same branch as r2. what is the current running through the battery? (d) what is the power dissipated in r3?
