Introduction

[@radiantfoxengineering797]

A= (pi/4 )* (.008m)^2

[@amerikanracer3301]

question. A = (pi/4)*(r)^2. why is it we are taking the whole diameter but not the radius?

[@laughtherapey]

why arent we taking reactions?

[@radiantfoxengineering797]

The reason we do not take reactions:
- Rigid beams with everything on equilibrium.
- The problem is statically determinate.
- Only looking for force AB.

how do you calculate -490.5+ FAc(3/5)?
