SUMMARY

The discussion centers on the torque relationship between gears of different sizes, specifically comparing a 20-tooth gear driving a 60-tooth gear versus a 60-tooth gear driving another 60-tooth gear. The torque produced by the 20-tooth gear to the 60-tooth gear is not the same as that produced by the 60-tooth gear to another 60-tooth gear due to the differences in gear ratios and effective radii. The concept of lever arms is crucial in understanding how torque is transmitted through gears.

PREREQUISITES
  • Understanding of gear ratios
  • Knowledge of torque and its calculation
  • Familiarity with the concept of lever arms
  • Basic principles of mechanical advantage
NEXT STEPS
  • Research gear ratio calculations and their impact on torque
  • Learn about the principles of mechanical advantage in gear systems
  • Explore the concept of effective radius in gear interactions
  • Study torque calculations in mechanical systems using formulas
USEFUL FOR

Mechanical engineers, students studying mechanics, and anyone interested in understanding gear systems and torque relationships.

Hello
so here is the problem that I'm confused with:
let's say...

Will a torque produced by a 20 teeth(force is exerted to this one) to 60 teeth gear be the same torque compared to a 60 teeth(force is exerted to this one) to a 60 teeth gear.

My torque is infinite, my friend.
 
Calculate the effective radius of the contact points on the theeth of the two gears, and use your knowledge of lever arms.
