1.	A copper and a tungsten plate having a thickness δ = 2mm each are riveted together so that at 0∘C they form a flat bimetallic plate. Find the average radius of the curvature of this plate at t = 200∘C. The coefficient of linear expansion for copper and tungsten are αCu = 1.7 × 10−5/K and αW = 0.4 × 10−5/K.
Answer» A copper and a tungsten plate having a thickness $δ$ = 2mm each are riveted together so that at $0^{\circ} C$ they form a flat bimetallic plate. Find the average radius of the curvature of this plate at $t$ = $200^{\circ} C$ . The coefficient of linear expansion for copper and tungsten are $α_{C u}$ = $1.7 \times 10^{- 5} / K$ and $α_{W}$ = $0.4 \times 10^{- 5} / K$ .

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?
