Q. 11.9 A brass wire long at is held taut with little tension between two rigid supports. If the wire is cooled to a temperature of what is the tension developed in the wire if its diameter is ? Co-efficient of linear
Youngs Modulus of Brass,
Co-efficient of linear expansion of Brass,
The diameter of the given brass wire, d = 2.0 mm
Length of the given brass wire, l = 1.8 m
Initial Temperature T1 = 27 oC
Final Temperature T2 = -39 o C
The tension developed in the wire is 378 N. The negative sign signifies this tension is inward.
