Carpenter


Whether constructing houses or building furniture or cabinets, carpenters spend a good portion of their time as mathematicians, particularly geometers . Before starting work on a project, they have to be able to calculate the correct amount of materials they need. Once work begins, they have to measure materials accurately, and calculate lengths, areas, angles, etc., to create a finished product.

Sometimes the mathematics that carpenters use is relatively easy. Using simple arithmetic, a carpenter can, for example, calculate the number of twoby-four studs needed in a wall of a given length when the studs are 16 inches apart, being sure to include the extra two-by-fours needed around doors and windows and at the top and bottom of the wall.

Sometimes, though, the mathematics of carpentry is more complicated. A carpenter building a staircase, for example, is faced with the difficult problem of making sure that each step is the same width, that the rise of each step is the same, and that the stairway fits into the space available without being too steep or too shallow. Similarly, in building a roof, a carpenter has to calculate the slope of the roof accurately, and then cut materials to make sure they conform to the slope and fit precisely.

Fortunately, carpenters have tools to help with these types of mathematical problems. One is a carpenter's square, which is a right-angle ruler with calibrations that measures angles. The other is a construction calculator, which is programmed to solve construction problems and gives measurements in eighths and sixteenths of inches rather than in decimals.
