Measuring and marking out

Published in Roger Timings, Fabrication and Welding Engineering, 2008

Fabrication, sheet metal and welding engineers rarely have to work to the fine limits and close tolerance of size that the mechanical engineer requires: the exception being when fitted bolts are required when assembling structures. When you measure length, you measure the shortest distance in a straight line between two points, lines or faces. It doesn’t matter what you call this distance (width, thickness, breadth, depth, height and diameter) it is still a measurement of length.

In the English system, length units are miles, yards, feet, and inches. Another system is the SI system. SI stands for the Système International (International System, in English). The metric system is part of the SI system. The basic unit of length in SI is meter. All units of length are based on it.

The dimensions of the MBB represent the three main dimension sizes, as commonly for example used by Masad et al. (2005), Al-Rousan et al. (2007), and Kutay et al. (2011). They are referred to as longest dimension () or length, intermediate dimension () or width and shortest dimension () or thickness in the following. With these three dimensions, several basic form indices can be calculated. This definitions of the aggregates' dimensions are shown in Figure 10(a), where an example aggregate can be seen, framed by an MBB.
