Bending&shear$2$ Q$248\mathrm{.}928571428571$

A symmetrical I$-$beam is subject to a shear force of $27468$ N acting along its entire length.

The beam has two flanges each with a width $21$ mm and depth of $13$ mm $.$

The width of the central web is $7$ mm and its depth is $60$ mm $.$

Determine the neutral axis position from the bottom face of the beam $($Answer in mm$).$

Determine the $1$st moment of area for the beam with respect to the neutral axis $($Answer in

$m{m}^3).$

Determine the maximum shear stress in the beam $($Answer in Pa$).$

Determine the maximum shear stress at the joint between the flange and web $($Answer in

kPa $).$
