Mechanical Engineering QUESTION #2466
Question 1
The addendum of a standard full-depth involute gear tooth in SI units (module \(m\)) equals:
  • \(a = 1.25m\)
  • \(a = m\)✔️
  • \(a = 0.8m\)
  • \(a = 1.157m\)
Correct Answer Explanation
For standard full-depth involute teeth (SI, 20° pressure angle): addendum \(a=m\) (one module), minimum dedendum \(b=1.25m\).
