Wood - Physical Properties

Credit: 3 PDH

Course Fee: $45.00

25 Pages


Course Summary

Wood exchanges moisture with air; the amount and direction of the exchange (gain or loss) depend on the relative humidity and temperature of the air and the current amount of water in the wood. This moisture relationship has an important influence on wood properties and performance. This chapter discusses the physical properties of most interest in the design of wood products.
