Two steel rods of 20 mm diameter are joined end to end by means of a turn buckle as shown in figure, other end of each rod is rigidly fixed. Initially, there is no tension in each rod. Effective length of each rod is 5 m. Threads on each rod has a pitch of 2.4 mm. Calculate the increase in tension when the turn buckle is tightened by one third of revolution. E = 208 GPa. If the temperature of the rods is increased, then at what temperature, tension in each rod is reduced to half of its magnitude. αs = 11 x 10−6/℃.

Two steel rods of 20 mm diameter are joined end to end by means of a ...
A turn buckle is a type of nut having internal threads on two ends but in opposite directions. Ends of tie rods are inserted from both the sides as shown. By rotating the turn buckle, both the tie rods are tightened.
Length of each rod = 5 m Pitch of thread = 2.4 mm
Axial movement of rods on both the sides = 2.4/ 3 = 0.8 mm
Strain in each rod = 0.8 / 5000 = 0.16 x 10−3
E = 208000 N/mm2
σ, stress in each rod
= 0.16 x 10−3 x 208 x 1000 = 33.28 N/mm2
Area of cross–section of each rod,
A =π / 4 x 202 = 100 π mm2
Tension in each rod, T = 100π x 33.28
= 10455 N
= 10.455 kN
Tension in rod is to be reduced to half by increasing the temperature of the bar
