Question

From the beam shown below, determine the following:

Maximum bending stress of the beam if the beam has a square cross section 300 mm by 300 mm
Maximum bending stress of the beam if the beam has a rectangular cross section vwith base 200 mm and height 500 mm

Calculate for the problems, Draw FBD, include proper units/dimensions and answers must be in 3 decimal places.

500 kN
100 kN/m
500 kN/m
5 m
2 m
3 m
10 m

The Flexure Formula
Rearranging..
Where:
Omax = max normal stress in the member which occurs
at a point on the cross-sectional area farthest away
from the neutral axis.
Mc
M = the resultant internal moment acting about the
Отах
neutral axis.
c = perpendicular distance from the neutral axis to a
point farthest away from the neutral axis.
| = moment of inertia of the cross sectional area
about the neutral axis.
