Discussion Overview

The discussion revolves around determining the torque ratio for a set of gears with a specified gear ratio of 3.2:1. Participants explore the implications of gear ratios on torque and seek clarification on the calculations involved.

Discussion Character

  • Technical explanation, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant asks for the torque ratio corresponding to a gear ratio of 3.2:1 and requests an explanation of how to arrive at that answer.
  • Another participant questions the meaning of gear ratio and its effect on applied torque.
  • A different participant presents multiple options for the torque ratio based on the gear ratio of 3.2:1 and seeks guidance on the calculation method.
  • One participant states that if the gear ratio is 3.2:1, then the torque ratio is 1:3.2, explaining that the output shaft will have 3.2 times the torque of the input shaft under certain conditions.
  • A participant identifies themselves as an automotive service technician, indicating their practical experience rather than an academic inquiry.

Areas of Agreement / Disagreement

The discussion contains multiple viewpoints regarding the torque ratio, with one participant asserting a specific torque ratio of 1:3.2 while others present different interpretations or seek clarification. No consensus is reached on the calculation method or the implications of the gear ratio.

Contextual Notes

Participants express uncertainty about the definitions and calculations related to gear ratios and torque ratios, indicating a need for further clarification on these concepts.

Here is my question that I haven't been able to solve.
What would the torque ratio be for a set of gears with a gear ratio of 3.2:1?
And how did you come up with the answer?
 
Physics news on Phys.org
what does a gear ratio mean?
If you apply a torque to a set of gears how does the gear ratio effect that?
 
This is my question.Two gears have a turning ratio of 3.2:1 What is there torque ratio ?
.32:1
1:3.2
3.2:1
32.0:1
And how would you calculate that??
 
By the way I am a 55 year old Automotive service tech so I don't have homework. Just trying to resolve a issue.
 
If the gear ratio is 3.2:1, then the torque ratio is 1:3.2. The output shaft will have 3.2 times the torque of the input shaft if the input shaft rotates 3.2 times every time the output shaft rotates 1 time. Power remains the same except for drivetrain losses.
 
Thank you for your time Jeff
