Application +4 | -1

A uniform steel bar of cross-sectional area

A

and length

L

is suspended, so that it hangs vertically. The stress at the middle point of the bar is

(\rho

is the density of steel)

View answer and explanation

Correct option: B

\frac{L \rho g}{2}

Option B (

\frac{L \rho g}{2}

) is correct because the stress at the middle point depends on the weight of the lower half of the bar.
