Macaulay's Method for a Timoshenko Beam [PDF]
International Journal of Mechanical Engineering Education, 2007 The Macaulay bracket notation is familiar to many engineers for the deflection analysis of a Euler–Bernoulli beam subject to multiple or discontinuous loads. An expression for the internal bending moment, and hence curvature, is valid at all locations along the beam, and the deflection curve can be calculated by integrating twice with respect to the ...
