For a construction grade Spruce Pine Fur 2 x 4 section, the reference design value for bending stress is ________ psi.  (Provide the exact value as you find in the applicable table from the book/slide.)

For a B-B Structural I form of 11/16-inch thickness and 12-inch width, the rolling shear constant when used with the face grain perpendicular to the span is _____ in. (Provide the exact value as you find in the applicable table from the book/slide.)

For a B-B Structural I form of 7/8-inch thickness and 12-inch width, the moment of inertia when used with the face grain parallel to the span is _____ in. (Provide the exact value as you find in the applicable table from the book/slide.)

The adjusted rolling shear design value for a structural I plywood (used wet) is _______ psi. Consider short-term loading duration.

Given: Spacing of stringers = feet Span length of stringers = feet Total form vertical design load for strength =  lb/ft2 Adjusted design value for bending stress =  lb/in2 Find the required section modulus (in3) for the stringer based on the bending criteria. Consider equations for 3-span continuous beam. ***Consider at least two decimal places during calculation.
