Question 78 Statics | Mechanical advantage | difficulty level 1Two gears are meshed together, with Gear A having 8 teeth and Gear B having 24 teeth. If a torque of 20 Nm is applied to Gear A, what is the theoretical mechanical advantage of this gear system? 4 0.33 0.25 3 Report this questionExplanationThe theoretical mechanical advantage of a gear system can be calculated using the ratio of the number of teeth on the driven gear (Gear B) to the number of teeth on the driving gear (Gear A): $$MA = \frac{24}{8} = 3$$ The mechanical advantage of 3 means that the gear system multiplies the input torque by 3, assuming no losses due to friction or other factors. The torque value of 20 Nm is not used in determining the answer to this question.Your Results Restart with New Questions Change Quiz Settings Review the Questions
