Bearing Apps, Specs & Data Mechanical Tolerances Specs This applies only to loads . References Cast irom, ASTM A48, structural steel fro bridges and structures, ASTM A7. When forces cause a compression of an object, we call it a compressive stress. Strain is the "deformation of a solid due to stress" - change in dimension divided by the original value of the dimension - and can be expressed as, = dL / L (1), dL = elongation or compression (offset) of object (m, in), Stress is force per unit area and can be expressed as, = F / A (2), = (F / A) / (dL / L) (3), E = Young's Modulus of Elasticity (Pa, N/m2, lb/in2, psi). For example, a stress on a rubber band produces larger strain (deformation) than the same stress on a steel band of the same dimensions because the elastic modulus for rubber is two orders of magnitude smaller than the elastic modulus for steel. In the remainder of this section, we study the linear limit expressed by Equation \ref{12.33}. You can target the Engineering ToolBox by using AdWords Managed Placements. Downloads . 10000 psi can be converted to 0.069 GPa and 10 ksi as indicated in the chart below: Note! Thermodynamics However, under other circumstances, both a ping-pong ball and a tennis ball may bounce well as rigid bodies. Hence, Steel is more elastic than rubber. What is the tensile strain in the wire? Yield strength is defined in engineering as the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation. Young's modulus can be used to predict the elongation or compression of an object. These tables are valuable references for industry and for anyone involved in engineering or construction. Youngs modulus is a fundamental mechanical property of a solid material that quantifies the relationship between tensile (or compressive) stress and axial strain. For designing the load-carrying capability of steel and concrete structures. The pillars cross-sectional area is 0.20 m2 and it is made of granite with a mass density of 2700 kg/m3.
