Attic beam measurement.

Step 3 screw an eye hook into the beam where you made the mark. Attic floors with limited storage l 240 10 psf. Strength of a material is obviously important. Fortunately this is a fairly easy fix.

On longer spans the beam may require much more bearing space as indicated by this table. Our 12 ft long beam was made from doubled 11 7 8 in wide x 1 3 4 in thick lvls laminated veneer lumber a very common strong type of beam that looks exactly like thick plywood boards.

Attach a pulley to it by sliding the pulley s hook into the eye. The formula for the section modulus is beam width times beam depth squared divided by 6.
