	Tension is a state of stress in which a material is being pulled apart, for example a cable that is attached to a ceiling with a weight fixed to its lower end. Under the influence of gravity, the weight exerts a downward pressure that produces tension in the cable, as does the reaction at the fixing point in the ceiling.

		+
		+	In both the above cases, the fibres become longer as a result of the weight applied. When a unit length of material becomes elongated, it is termed ‘tensile strain’.
		+
		+	As long as the cable is not stressed above its elastic range, the extent of lengthening will depend on its cross section, its length and the load applied. The larger the cable diameter, the smaller the unit elongation. Experiments have shown that elongation is inversely proportional to the area, so a member of 20mm2 cross-sectional area will stretch half the amount of a member of the same material that is 10mm2.
		+
		+	Hooke’s Law states that an increase in the load produces a proportionate increase in elongation and that this elongation is directly proportional to the length of the member. So, for a given load and given length of member, a member 2m-long will stretch twice as much as a 1m-long member of the same material.
