In this article, (and video above), we calculate what torque is transmitted by the shaft of a gear to give you a better understanding of what you can expect during the FE Exam.
Question:
Two meshing spur gears are arranged such that neither gear is turning and both are in equilibrium. A small gear has a radius of 4 cm. The shaft of this small gear carries a torsional moment of 75 N∙m from an external motor. A larger gear has a radius of 20 cm. Assuming a 100% transmission of efficiency, what torque is transmitted by the shaft of the larger gear?
