MecMovies 4.0 : M6.13: Two Shafts Connected by Gears

scene 6 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. A torque of 342.5 Newton meter is applied on gear of 100 millimeter diameter. An internal torque T subscript 1 in applied on A B toward B. Parameters: d = 35 millimeter, G = 80 gega Pascal, T = 685 Newton meter.

Assume a positive internal torque in shaft $(1)$ . From the free-body diagram, write the equilibrium equation:

$\sum_{} M_{1} = - 342.5 N - m - T_{1} = 0$

$∴ T_{1} = - 342.5 N - m$
