$2\mathrm{.}10$ Why are engineered wood design values larger?

a$.$ They are larger members.

b$.$ The process can be controlled.

c$.$ They are sized for demand.

d$.$ They can be cambered.

$2\mathrm{.}11$ Which statement is true about beam deflection?

a$.$ Wood has a tendency to creep

b$.$ For longer spans, strength usually controls over deflection.

c$.$ Increasing beam width is the most economical way to reduce deflection.

d$.\frac{11}{2}xx\frac{51}{\frac{?}{?}}{4}^{\text{'}\text{'}}$

$2\mathrm{.}12$ Which of the following statements about wood columns is false?

a$.$ The greater the length to depth ratio, the lower the allowable compressive stress due to buckling.

b$.$ Compressive stress is based on the slenderness ratio.

c$.$ The actual compressive stress is determined by dividing the axial force by the cross sectional area.

d$.$ None of the above are true.
