Converting Effective Mechanical Load to Newtons (Capybara)

Click For Summary

Discussion Overview

The discussion revolves around converting the Effective Mechanical Advantage (EMA) of capybaras into a force output in Newtons to determine how many capybaras would be needed to overcome a specified frictional force. The context includes theoretical considerations and practical applications related to animal biomechanics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant states that the EMA of a capybara is 0.71 and their mass is 55 kg, with an average speed of approximately 3.0 km/h.
  • Another participant mentions that EMA is defined as Fload/Feffort and attempts to rearrange this to solve for the Force of Effort, expressing confusion over the calculations.
  • A participant questions whether there is already an ongoing thread addressing these questions, suggesting continuity in the discussion.
  • One participant clarifies their intention to start a new thread due to new findings, indicating a desire to keep discussions organized.
  • Another participant requests clarification on the acronym EMA and its units, emphasizing the need for clear definitions in the discussion.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the calculations or the definitions involved, and multiple viewpoints regarding the handling of the topic remain present.

Contextual Notes

There are unresolved aspects regarding the conversion of EMA to force output, including potential missing assumptions and the need for clarity on units. The discussion also reflects varying levels of familiarity with the forum's structure and expectations.

TL;DR
I have the EMA of the average capybara, and I'm trying to figure out the maximum force one can exert given that EMA.
Hello again!
I've found the capybara's EMA to be 0.71. Their mass to be 55kg. And their average speed to be ~3.0km/h.

I want to figure out how many capybaras it would take to overcome Friction * Normal force of ~125,000N. How would I go about doing that?

The answer of a Quora question states:
EMA of a capybara is around 0.7. That would give us a force output of around 700N.

But I have no idea how they converted from EMA to a force output in Newtons. Can anyone help me?
 
Engineering news on Phys.org
I know that EMA is = Fload/Feffort

I thought I could rearrange the variables to solve for the Force of Effort. But that obviously didn't work. A capybara cannot pull 88750N.
 
Don't you already have a thread going on this set of questions?
 
I do, but I figured out some stuff since and it felt like a different question? I assumed for a different question, I'd make a different post :) Sorry, new to this forum.
 
No worries. Please keep this discussion in your original thread. Otherwise it gets too confusing and fragmented for others to keep up. Thanks. :smile:
 
Oh, and please define the acronym EMA unless it's obvious in your other thread (I don't remember), and if EMA has units, please include those. Thanks. :smile:
