A 20 foot long 6 x 12 beam supports floor joists in the interior of a residence spaced every 8 feet. Assume the DL=10 psf, LL=40 psf 1. Calculate the span.

2.Calculate the beam bending moment. Le=, RB= 3 Provide all the load factors. 4. What is the Bending Stress? Is this acceptable? 5.What is the Shear Stress? Is this acceptable? 6. What is the total deflection? Is this acceptable? 7. What is the live load deflection? Is this acceptable? 8. What is the bearing stress? Is this acceptable?
