THE COEFFICIENT OF LINEAR thermal expansion (CTE, a, or a1) is a material property that is indicative of the extent to which a material expands upon heating. Different substances expand by different amounts. Over small temperature ranges, the thermal expansion of uniform linear objects is proportional to temperature change The relative expansion (also called strain) divided by the change in temperature is called the material's coefficient of linear thermal expansion and generally varies with temperature. As energy in particles increases, they start moving faster and faster weakening the intermolecular forces between them, therefore expanding the substance Find the coefficient of thermal linear expansion Refer to manufacturer published specifications to find the coefficient of thermal linear expansion.

The coefficient of linear expansion is the change in length of a specimen one unit long when its temperature is changed by one degree (see linear expansion). Different materials expand by different amounts. Just how much a particular material expands depends on the forces of cohesion between neighboring atoms or molecules The linear thermal expansion - the change in length - of an object can be expressed as. dl = L 0 α (t 1 - t 0) (1) where . dl = change in object length (m, inches) L 0 = initial length of object (m, inches) α = linear expansion coefficient (m/m o C, in/in o F) t 0 = initial temperature (o C, o F) t 1 = final temperature (o C, o F) Coefficient of Linear Expansion is the rate of change of unit length per unit degree change in. Increase in length = Lo × α × t where Lo is the original length, α is the coefficient of linear expansion, and t is the increase in temperature. With the aid of this equation it is easy to solve the bridge problem we posed earlier

They are thought to have a coefficient of linear thermal expansion instead of a coefficient of volume thermal expansion. This coefficient acts the same as the three-dimensional coefficient of expansion, except it corresponds to the fractional increase in length (instead of volume) per degree temperature What is the Linear Expansion Coefficient? The term expansion refers to a shift or increase in duration. Linear expansion is defined as a change in length along one dimension (length) over a volume. The change in temperature is the cause of the expansion in this case. As a result, it is assumed that a change in temperature would result in.
