(see CDL 3.17) A carpenter has a wooden plank of length L and a constant weight uo per unit length. He wishes to cut a smaller plank of length I. The cut is the smoothest where the bending moment is zero. He puts one sawhorse (modelled as a pin) at r 0. Where should he put the second sawhorse (a) such that the bending moment at z l is nero? Wo, force/unit length L

Matrix Algebra for Structural analysis

Structural analysis is a process in which the effects of different loads and internal forces, acting on structures and their elements are determined. This method of analysis is effective in detecting the failure loads of the structural elements and the design can be altered before commencing the construction process, which ensures proper strength and safety of the structures.
