Objectives
Strenght of materials is the continue of theoretical mechanics and is the basic for other disiplines such as the calculation of machining parts, applied mechanics, making moulds, hydraulics, pneumatics and others. The student learns to choose the right material, calculate the deformation, the several kinds of stresses and the most dangerous compounded stress.
