Topic: WAVE SUPERPOSITION Sound waves transfers energy to the surrounding molecules causing them to  vibrate. It can penetrate as long as there is a medium. But when you try to record a video or presentation, we would not want to have unnecessary background noise. One example is a recording studio where singers usually utilize to make a clear recording of their song. How does a recording studio work?

I have been working on this Solid Mech problem for a while and have gottem nowhere we are supposed to be finding the modulus of elasticity for a set of data (attached). I have made an excel sheet from this to finda stress strain graph. I understand how the modulus of elasticity is (E = (delta stress)/(delta strain)) but I cannot find the propotional limit that I need to find delta stress and delta strain

Q: Figure 2 shows a typical mast from a modern racing yacht. It is built in the form of a thin-walled tube (hallow cylinder). To win long-haul ocean races, these yachts need to have every advantage that high-performance materials can give, in terms of maximum stiffness (must not easily deflect), plus minimum weight as possible. The following are the equations to use: 1(F13 8 == 8 EI and I = ar³t, A = 2art assume l and cross section are fixed but thickness t is free to change. • Drive the performance index for this problem • Use table 1 to select top three materials with the best performance index.
