Unformatted text preview: ANS. (a) From slide 27 in the course notes on wood, we know the flexural strength of this species is 9200 psi. We also know that the M max will occur at the center span – for this loading condition – and will be PL/4 or 1500 in.-lbs. psi 125 , 1 ) 2 ( 12 1 ) 1 ( 1500 4 max = = σ which is considerably less than the strength, so the beam will not fail (b) " 27 . ) 2 ( 12 1 ) 10 26 . 1 ( 48 ) 60 ( 100 48 4 6 3 3 = = = = x EI PL deflection δ Question 3 How is the strength of wood generally affected by: (a) its moisture content (b) its specific gravity (c) temperature (d) loading rate (e) duration of loading (f) the presence of defects ANS.
