Tree Log Weight Formula:

A tree log is a cylindrical section of a tree trunk or large branch, typically used for construction, firewood, or woodworking. It is characterized by its circular cross-section and length. The weight of a log can be significant and is influenced by factors like its diameter, length, and the type of wood.

Wood density, which varies among different tree species, also plays a crucial role in determining the log’s weight. Denser wood types, like oak, are heavier than softer woods, like pine. The diameter of the log, often measured as the radius from the centre to the outer edge, affects the overall volume and, consequently, the weight of the log.

The formula for calculating the weight of a log is based on its cross-sectional area and length, accounting for the density of the wood. This formula allows for accurate estimates of weight, which can be useful in transportation, construction, and resource management.

The weight of a log is derived by multiplying the log’s cross-sectional area (calculated using the radius), length, and a density factor specific to the type of wood. The radius is typically converted from inches to feet to ensure consistency in measurements. The weight factor, 93.6, is used to account for the density of wood and units.

Weight, W_(lb) in grams can be calculated by multiplying pi, radius, R_(in) divided by 12 squared, total length, TL_(ft) in centimetres, and the constant 93.6.

Weight, W_(lb) = 3.14 * (R_(in) / 12)² * TL_(ft) * 93.6

W_(lb) = weight in pounds, lb.

R_(in) = radius in inches, in.

TL_(ft) = total length in feet, ft.

Tree Log Weight Calculation:

1.A tree log has a radius of 10 inches and a length of 8 feet. Calculate the weight of the log using the given formula.

Given: R_(in) = 10in, TL_(ft) = 8ft.

Weight, W_(lb) = 3.14 * (R_(in) / 12)² * TL_(ft) * 93.6

W_(lb) = 3.14 * (10 / 12)² * 8 * 93.6

W_(lb) = 3.14 * (0.8333)² * 8 * 93.6

W_(lb) = 3.14 * 0.6944 * 8 * 93.6

W_(lb) =1632.8lbs.

2.A tree log weighs 2000 lbs and has a radius of 15 inches. Determine the length of the log.

Given: R_(in) = 15in, W_(lb) = 2000lbs.

Weight, W_(lb) = 3.14 * (R_(in) / 12)² * TL_(ft) * 93.6

TL_(ft) = W_(lb) / 3.14 * (R_(in) / 12)² * 93.6

TL_(ft) = 15 / 3.14 * (15 / 12)² * 93.6

TL_(ft) = 15 / 3.14 * (1.25)² * 93.6

TL_(ft) = 4.36ft.
