A question about cantilever beam

Click For Summary

Discussion Overview

The discussion revolves around the analysis of a cantilever beam subjected to a uniform load, specifically focusing on the maximum displacement and deflection of the beam. The context includes parameters such as beam dimensions and applied forces, with a request for appropriate formulas and methods for solving the problem.

Discussion Character

  • Homework-related
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • The initial post presents a homework problem involving a cantilever beam with specific dimensions and loading conditions, seeking to determine maximum displacement and deflection.
  • One participant suggests consulting a textbook, specifically recommending chapter 9 of Stephen Senturia's Microsystems Design, indicating it may contain relevant information.
  • There are repeated inquiries about whether deflection is equivalent to displacement for a cantilever beam, with some participants expressing belief that they are the same in this context.
  • Clarification on the phrasing of the question regarding deflection and displacement is provided, suggesting a more direct approach to asking the question.

Areas of Agreement / Disagreement

Participants express uncertainty regarding the equivalence of deflection and displacement for a cantilever beam, with some suggesting they are the same while others seek clarification on the terminology used.

Contextual Notes

There are unresolved aspects regarding the definitions of displacement and deflection in the context of cantilever beams, as well as the specific formulas applicable to the problem posed.

Homework Statement


Im having a fixed end free end of cantilever beam under going a uniform load.
With the beam length ranging 0-750 micron,width of 10-20micron and thickness of 0.5 and 1.0 micron.While the force ranging from 0-50microNewton.

Homework Equations


what is the maximum displacement of the beam regarding to the y and z axis?
Is maximum displacement are equal to maximum deflection of the beam?
what is the appropriate formula in solving this problem?


The Attempt at a Solution


-Using COVENTORWARE 2006 software for simulation
-Normal calculation method for theory prooving...



Any idea?please help me...

Since this is probably for a microfabrication / devices course, I'd suggest a look through your textbook. Since it's likely Stephen Senturia's Microsystems Design take a look through chapter 9.
 
can i know whether the deflection are same as displacement for cantilever beam?

In this context, I believe so. BTW, it sounds as if you are asking if it is possible for you to know whether the deflection is the same as displacement. You should just ask, "Is the deflection the same as the displacement for a cantilever beam?"
