Can a 63mm Bore Pneumatic Ram handle the required weight at an angled position?

Click For Summary

Discussion Overview

The discussion revolves around determining whether a 63mm Bore Pneumatic Ram can handle a specified weight when positioned at an angle, as opposed to the straightforward case of being vertical. Participants explore the necessary calculations and concepts involved in analyzing forces in this context.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant expresses difficulty in calculating the weight capacity of the ram at an angle, having only managed to do so for a vertical position.
  • Another participant suggests that force is a vector and prompts the use of vector components to analyze the situation.
  • A participant confirms the idea of resultant forces, indicating a need to express the total force as a sum of its components, specifically vertical and horizontal forces.
  • Further clarification is sought regarding the fixed and moving parts in the diagram, with a request for a more detailed description of the problem to facilitate assistance.
  • A later reply emphasizes the need for clearer visuals in the sketch and introduces the principle of virtual work as potentially relevant to the problem.

Areas of Agreement / Disagreement

Participants appear to agree on the need for a clearer understanding of the problem and the application of vector analysis, but no consensus exists on the specific calculations or approaches to take for the angled position.

Contextual Notes

Participants note the importance of a detailed diagram and clear definitions of fixed and moving elements, but the discussion does not resolve the mathematical steps necessary for the calculations.

Hey

So I am still a beginner in Physics and work asked me today to calculate if a 63mm Bore Pneumatic Ram will do the required job. Anyway, so I know how to calculate the weight capacity the ram can handle if it is at a 90 deg angle however if the ram is on an angle then I am stuck. I need to get back to them today and as a part student, I am finding this hard. any help would be awesome :)

I have attached a sketch of the layout and how i calculate the weight capacity calculations i have done.

Force is a vector. Do you know how to write a vector as a sum of components?
 
You meaning like a resultant force where Fnet=F1+F2?

Sort of, but working backwards in this case: you know the total force already and you need to write it as the sum F1 and F2, where one of these is vertical and one is horizontal. You'll need some basic trigonometry (what ##\sin## and ##\cos## mean) as well.
 
In your diagram what is fixed and what is moving and in which directions ?

If you can describe the problem more completely I'm sure we can help you solve it . A realistic pictorial sketch would be very useful .

As an old man, I'd like to second Nidum's request, and add that the figure needs to be more sharp with darker lines.

From the little I could see, this looks like a prime application for the principle of virtual work.
