General Engineering Principles ISealed Source & Device WorkshopGeneral Engineering Principles I: 1 General Engineering Principles IForces:Tensile and Compressive: Tensile (Tension) - pulling apart Compressive (Compression) - pushing together Forces may be direct, or may be caused by changes in pressure, temperature, or combined : Force perpendicular to the primary Source & Device WorkshopGeneral Engineering Principles I: 2 General Engineering Principles IStrength: Stress = Force/Area (psi or Pa) Strain = Elongation under stress =change in length/original length (in /in )length/original length ( ) Ultimate Strength: maximum stress sustained without breaking - exceed this limit and the material will break. Yield Strength: maximum stress sustained without permanent deformation - the material will stretch and come back to its original Source & Device WorkshopGeneral Engineering Principles I: 3 General Engineering Principles IStress vs.
• Twisting of a component around it primary axis. • Usually applies for turning a shaft, such as a shutter. • The larger the lever arm, the greater the torque. • A large weight that rotates at a large distance from the center of a shaft will create a large torque.
