Abstract

A wooden rack for carrying a load on human's back was investigated by using a primary way of material mechanics in order to find out some mechanical meanings of the wooden rack's shape. The wooden rack was modeled with FEM to be simulated to reproduce the situation where someone would shoulder it with a weight. The characteristics of the stress distributions on the wooden rack calculated by the FEM was applied to get a simple material mechanics model to formulate the distributions of axis, share forces, and bending moments with some equations, which would be induced in the wooden rack by the weight in the situation. And, equivalent stress shapes where the maximum stresses are equal on the overall surfaces of the rack were presumed by using the equations describing numerically the internal forces: axis, share and moment to compare the calculated shapes and the real shape of the wooden rack.
