Assignment $7$

Determine the average shear stress developed in the nails within region AB of the beam. The nails are

located on each side of the beam and are spaced $100mm$ apart. Each nail has a diameter of $4mm.$ Take

$P=7kN,$ and show the shear diagram $($SD$),$bending moment diagram$($BMD$)$ and shear stress over the

beam section.$($Read the examples$)$ Ans. $I=53\mathrm{.}3{10}^{6}m{m}^{4}F=239N$
