Question
The beam is constructed from two boards fastened together at the top and bottom with three rows of nails spaced every 4 in. If each nail can support a 400 -lb shear force, determine the maximum shear force $V$ that can be applied to the beam.
Step 1
Substituting $b = 9$ and $h = 6$ into the formula, we get $I = \frac{9 \times 6^3}{12} = 162$. Show more…

The beam is constructed from two boards fastened together at the top and bottom with three rows of nails spaced every 4 in. If a shear force of $V=900$ lb is applied to the boards, determine the shear force resisted by each nail.
The beam is constructed from two boards fastened together at the top and bottom with two rows of nails spaced every 6 in. If each nail can support a 500 -Ib shear force, determine the maximum shear force $V$ that can be applied to beam.
The beam is constructed from three boards. If it is subjected to a shear of $V=5$ kip, determine the maximum allowable spacing $s$ of the nails used to hold the top and bottom flanges to the web. Each nail can support a shear force of $500 \mathrm{lb}$
