Question

A prismatic bar of uniform cross-sectional area of $5c{m}^2$ is subjected to axial loads as shown in the given figure.



Portion BC is subjected to an axial stress of

• A. $400kg/c{m}^2$ tension
• B. $2000kg/c{m}^2$ compression
• C. $1000kg/c{m}^2$ tension
• D. $600kg/c{m}^2$ tension

Answer 1

The correct option is C $1000kg/c{m}^2$ tension

Axial load on portion $BC=3000+2000=5000kg$ (tensile)
$Tensilestress=\frac{5000}{5}=1000kg/c{m}^2$
