Calculating normal stress in a beam

Click For Summary
SUMMARY

The discussion focuses on calculating normal stress in a beam, with specific calculations provided by a user. The area of the beam is calculated using the formula area = (π)(9^2), resulting in 254.46. The user determines the center of gravity (CG) as 25 kN based on the equation Cos53.13 = 15/CG. The normal stress is then calculated as 98.25, although the unit of measurement is not specified, highlighting the importance of including units in calculations.

PREREQUISITES
  • Understanding of normal stress calculations
  • Familiarity with geometric area calculations
  • Knowledge of trigonometric functions in engineering
  • Ability to interpret and apply units in engineering calculations
NEXT STEPS

Hello

So I've done some calculations, I'd like to see if my stuff is right. Thanks :)

Please view attached http://i.imgur.com/AfMZyr0.jpg

area = (pi)(9^2) = 254.46

Cos53.13=15/CG
CG=25kN

Normal stress = 25000/254.46
=98.25

You must train yourself to show units with your calculations. You show the normal stress as 98.25 what?
