Quizplus · Accepted Answer

The dedendum of a spur gear is calculated using the formula: Dedendum = 1.25 / Diametral Pitch. The Diametral Pitch is calculated as the number of teeth divided by the pitch diameter. Here, Diametral Pitch = 48 / 3 = 16. Therefore, Dedendum = 1.25 / 16 = 0.078125. However, the closest option provided is 0.3857, which is likely a miscalculation or misinterpretation of the question.
