Power(hp) needed for climbing an inclined plane

Click For Summary

Discussion Overview

The discussion revolves around calculating the power required for a 1-ton tracked vehicle to climb a 40° incline at a speed of 10 kph. It touches on the physics involved in this calculation, including factors like vehicle weight and engine efficiency.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant asks for the power needed for a tracked vehicle to climb a hill, indicating a lack of physics background.
  • Another participant emphasizes that the question is indeed physics-related and requests more context about the inquirer’s background and purpose.
  • A later reply provides additional context about the inquirer's project, detailing the construction of a 1:4 scale model of an M4 Sherman tank and the intended use of an internal combustion engine.
  • One participant notes that the calculation is more complex than it appears, suggesting that factors such as the efficiency of power transfer from the engine to the treads must be considered.

Areas of Agreement / Disagreement

Participants generally agree that the question involves physics, but there is no consensus on the specific calculations or factors that need to be addressed.

Contextual Notes

Participants have not yet resolved the specific assumptions regarding power calculations, such as the efficiency of the engine and the mechanics of the vehicle's movement.

how much power(hp) would a 1-ton tracked vehicle need to climb 40° hills at 10kph. I know that this isn't exactly a physics question but I know that solving it involves physics to a certain extent.

It is completely a physics question, but it is of a form where it is required, on this forum, that you make some effort on your own. What is your background? What is your need to figure this out? I assume you are implying that this is not a homework question.
 
I am sorry for my lack (no) of content in describing the need for this question- the reason for which it that I didn't have much time to post it- and error that I will rectify now. The reason that I posted this is because I am building a 1:4 recreation of an M4 Sherman tank- of course, it won't be nearly as heavy as the real thing- but still a formidable 1000 lb. I want to equip it with an internal combustion gasoline engine and I would like to know the power needed for it.

I think that's a lot more complicated that your fairly straight-forward question suggests. You'll have to take into account the efficiency of transfer of power from the engine to the treads at the very least.
