3. En fritt upplagd balk med ett T-tvärsnitt utsätts för en punktlast 2Q och en utbredd last med den totala tyngden Q enligt figuren nedan. Beräkna den till beloppet största normalspänningen och skjuvspänningen som uppstår i livet av balken (area markerad i figur).

First, let's calculate the normal stress on the beam. Normal stress is defined as the force applied perpendicular to the cross-sectional area of the beam. Show more…

The beam $A B$ is subjected to the uniformly distributed load shown and to two unknown forces $P$ and $Q$. Knowing that it has been experimentally determined that the bending moment is $+800 \mathrm{N} \cdot \mathrm{m}$ at $D$ and $+1300 \mathrm{N} \cdot \mathrm{m}$ at $E,(a)$ determine $P$ and $Q,(b)$ draw the shear and bending-moment diagrams for the beam.

Relations Among Load, Shear, and Bending Moment
A simply supported wood beam $A B$ with span length $L=4 \mathrm{m}$ carries a uniform load of intensity $q=5.8 \mathrm{kN} / \mathrm{m}$ (see figure) (a) Calculate the maximum bending stress $\sigma_{\max }$ due to the load $q$ if the beam has a rectangular cross section with width $b=140 \mathrm{mm}$ and height $h=240 \mathrm{mm}$ (b) Repeat part (a) but use the trapezoidal distributed load shown in the figure part b.
