Materials

• Elasticity is the ability of a solid to regain its shape after distorting forces are released.
• Tensile forces stretch an object. Compressive forces compress an object.
• Brittle materials snap without any noticeable yield. Ductile materials can be drawn into wires.
• Elastic limit is the point on a stress strain graph where the object will become permanently deformed. Limit of the proportionality is the point at which the material stops following hookes law.
