ABSTRACT
Values of E and G are listed in Table 6.1 for various commonly used materials [10].
By the word beam, we mean a bar that is subjected to forces acting transversely to its axis. Beams are different from prismatic bars that are subjected to tensile and compressive forces because of the directions of the load that are applied to them. The loads on the bar act along its longitudinal axis. On the other hand, the loads on a beam act normal to its axis. Types of beams that are frequently studied include the cantilever beam and the simply supported (or simple) beam [10]. For a cantilever beam, one end of the beam is fixed and the other end is free (see Figure 6.11). At the fixed (or clamped) end, the
beam can neither translate (horizontally or vertically) nor rotate. However, at the free end, it may do both.
