Accounting for Gear Rotation  
scene 10 of 12
Diagram shows two shafts A B and C D of 35 millimeter diameter and 300 millimeter and 900 millimeter respectively, are connected using two gears, B with 100 millimeter diameter and C with 200 millimeter diameter. A torque T is applied at the end of C D at D. Parameters: d = 35 millimeter, G = 80 gega Pascal, T = 685 Newton meter.

When T is applied, the system of shafts and gears rotates and reaches equilibrium in the position shown.
