1.	An iron rod of length 1 m is fixed between two walls as shown in figure. Find thermal stress and thermal strain developed in the rod if it is heated by ΔT=20∘C(Given: Coefficient of linear expansion of iron is 1.2×10−5 ∘C−1; Young's modulus of iron is 2×1011 N/m2).
Answer» An iron rod of length $1 m$ is fixed between two walls as shown in figure. Find thermal stress and thermal strain developed in the rod if it is heated by $Δ T = 20^{\circ} C$ (Given: Coefficient of linear expansion of iron is $1.2 \times 10^{- 5}^{\circ} C^{- 1}$ ; Young's modulus of iron is $2 \times 10^{11} {N/m}^{2}$ ).

Two speakers S1 and S2 are derived from the same amplifier and placed at the same distance from x-axis as shown in figure. The speakers vibrate in phase at 680 Hz. A man stands at a point on the x-axis at a very large distance from the origin and starts moving parallel to the y-axis. The speed of sound is 340 m/s. Then, at what angle θ with the x− axis will the intensity of sound drop to a minimum for the first time?
