A material has a linear thermal expansion coefficient of 17 x 10-6 is 5.88m long at 28C. What is the change in length at 96C?
0,00679728mm
Why can linear equations and linear inequalities be solved the same way?
Somewhat, but the rules are a bit different for inequalities. Example. -2X > 4 X < - 2 See, sign changes when dividing by negative coefficient.
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
What is the coefficient in a linear equation?
anti- wank gloves.
What is the meaning of negative coefficient of x?
In the form y=mx+b, b is the y-intercept and m is the coefficient, so if an equation has a negative coefficient, m<0. As a graph, the slope of the line is negative.
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
Linear expansion apparatus?
Linear expansion apparatus is the apparatus used to measure the objects to these following properties: -> coefficient linear expansion -> coefficient thermal expansion -> specific gravity -> specific heat -> thermal conductivity -> thermal resistivity -> breaking strength and many others..
What material has the highest coefficient of linear thermal expansion?
nickel
What is the coefficient of linear expansion of mercury?
-39 degrees celsius to 450 degrees celsius
Why is it necessary to know the coefficient of linear expansion of solids?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.

The thermal linear expansion coefficient is positive when the material expands do you expect it be negative when the material contracts?
The coefficient remains positive, but the dT used will become negative, yielding a negative growth (ie, a contraction). See the equation below: dx = L * a * (Tactual - Tref) Where, L is the starting length a is the thermal expansion coefficient Tactual is the temperature you're evaluating at Tref is the reference (or starting) temperature If Tactual < Tref, then the quantity (Tactual - Tref) < 0
What is the thermal expansion coefficient for monel?
Thermal expanasion coefficient fro monel is 0,0000075 m/mºC. More info at http://www.engineeringtoolbox.com/linear-expansion-coefficients-d_95.html
Why are railroad tracks built with a flexible expansion and contraction joint?
The tracks have a larger coefficient of linear expansion than the ground beneath.
Does the coefficient of linear expansion depend upon length describe?
The coefficient of linear expansion DOES not depend on the length. Each material has a certain value for its coeeficient of linear expansion. The length of the material dictates how much it will expand linearly for a given rise in temperature. L" = L'(1 + a x (T'' - T')) That is the length at temperature T'' which is higher than temperature T' is given by the length L' at temperature T' multiplied by the quantity [1 + a x (T" - T')], where a is the coefficient of linear expansion which is constant for a given material. Thus if the temperature difference T" - T' is large then the expansion will be large which means L" - L' will be large. Likewise if the original length L' is large, then the corresponding expanded length L" will be large
Why is a bimetallic strip curve when it is heated or cooled?
Because the two metals have different coefficient of linear expansion
