Resolved Question:

#12. Spruce-Pine-Fir lumber weighs 26 lb/ft3. What is the weight in pounds per lineal foot of a 6” x 10” (actual dimensions: 5½” x 9½”) timber beam? What is the weight of the beam in kN/m and the mass in kg/m?

Weight in pounds per lineal foot = weight per cubic foot x dimension Weight in pounds per lineal foot = 26 x 6 x 10 Weight in pounds per lineal foot = 1560 lb/ft

Weight of the beam in kN/m:

1 lb/ft = 0.01459 kN/m 1560 lb/ft = 22.8 kN/m

Weight of the beam in kg/m:

1 kN/m = 101.9 kg/m 22.8 kN/m = 2324.2 kg/m

Spruce-Pine-Fir lumber weighs 26 lb/ft3. What is the weight in pounds per lineal foot of a 10"x10" (actual dimensions: 9 1/2" x 9 1/2") timber colum? What is the weight of the column in kN/m and the mass in kg/m?

Weight in pounds per lineal foot = weight per cubic foot x dimension Weight in pounds per lineal foot = 26 x 10 x 10 Weight in pounds per lineal foot = 2600 lb/ft

Weight of the beam in kN/m:

1 lb/ft = 0.01459 kN/m 2600 lb/ft = 37.93 kN/m

Weight of the beam in kg/m:

1 kN/m = 101.9 kg/m 37.93 kN/m = 3865.1 kg/m
