PASSAGE 10 The Thousand and One Nights Quote:“Stories save lives, for wisdom hidden in a tale can soften even the hardest heart.” What is the main idea of this passage?

Select the best choice(s) of dimensional lumber floor joists for the following spans.  Make choice for grades, No. 1 and No.2 using Southern Pine Span Tables.LL = 50 psf, DL = 10 psf, span = 12’    spacing=16”o.c.

The weight (lb/ft3) for a saturated stiff, Fat clay is

Axial Load (kips): 118Unbraced Length: 12

Determine the allowable bending stress (Fb) and allowable Compression parallel to the grain (Fc) for a Douglas Fir-Larch 2 x 10 No. 2, used in repetitive framing with snow loading.

Find the actual deflection of a 15 ft. long 10×16 wood beam with E=1,700,000 psi and Fb=1600 psi, carrying a total uniformly distributed load of 20 kips.  Find the maximum deflection for this beam under its maximum loading.

50 ksi steel, by Calculation: Select the lightest W section for a beam 20 ft in length with a superimposed total uniformly distributed live load of 98 kips and a total uniformly distributed dead load of 50 kips. DO NOT adjust for beam self weight.

Which material is the stiffest according to typical values of Modulus of Elasticity(E)?

What are the allowable stress values for the following lumber sections? (Based on Douglas Fir-Larch – Textbook)
