1.	A bar of length L0=3.77 m is placed on two rigid supports as shown in the figure. As a result of rise in temperature by 32 ∘C , bar cracks at its centre and buckles upward as shown in the figure. The fixed distance between the supports is also L0=3.77 m and coefficient of linear expansion of the bar is 25×10−6/ ∘C. Find the rise x of centre of the bar.
Answer» A bar of length $L_{0} = 3.77 m$ is placed on two rigid supports as shown in the figure. As a result of rise in temperature by $32^{\circ} C$ , bar cracks at its centre and buckles upward as shown in the figure. The fixed distance between the supports is also $L_{0} = 3.77 m$ and coefficient of linear expansion of the bar is $25 \times 10^{- 6} /^{\circ} C$ . Find the rise $x$ of centre of the bar.

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?
