Multiple choice general knowledge science & technology

  1. If a 20 teeth gear is meshes with 40 teeth gear then which is a weaker gear in bending if both the gears are made up of same material

  1. both weaker

  2. 20 teeth

  3. 40 teeth

  4. Any one depending on load
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In gear mechanics, the gear with fewer teeth has smaller individual teeth that are weaker in bending strength. Since both gears are made of the same material, the 20-tooth gear has smaller, weaker teeth compared to the 40-tooth gear. The 40-tooth gear has more teeth distributing the load, making it stronger. Load distribution depends on tooth size and number.
