Comparison of a particle

  • #1

Homework Statement



Concentrated forces are to distributed forces as particles are to
A. Objects
B. Rigid bodies
C. Planets
D. Solids

Homework Equations






The Attempt at a Solution



I say B I have looked up the definition of a rigid body and it seems a particle can be considered a rigid body in statics/mechanics due to the fact that there is no deformation in both when forces are applied

Sounds right to me, although my reasoning is different than yours.

I'm looking at it purely as an "is like" problem. I see a concentrated force as localized and a dispersed force as spread out and I see a particle as very local and a rigid body as spread out. I don't see any need to consider deformation. BUT ... that's just the way I look at it. Your analysis might be better.
