You are given a number of 32 Q resistors, each capable of dissipating only 1.8 W without being destroyed. What is the minimum number of such resistors that you need to combine in series or in parallel to make a 32 Q resistance that is capable of dissipating at least 14.0 W? Number i Units

1. Piezoelectric materials are often used as sensor materials because they transform mechanical deformation to electrical charge. Figure 1 shows an electric circuit of a piezoelectric sensor. The piezoelectric material is modeled as a current source in parallel with a capacitor. The resistance models the impedance of an amplifier. The goal is to make the output voltage v(t) proportional to the input charge q(t), so that we can use the voltage v(t) to measure the charge q(t). The ODE governing the input and output is dv RC +v=R- dt Ddq dt (1) where q(t) is the input and v(t) is the output. (a) Determine the frequency response function G(w). You can leave it as a fraction of two complex numbers. (b) Find the magnitude of the frequency response function G(w). (c) Show the asymptotic behavior of G(w) when w <1/RC and when w≫ 1/RC. (d) Plot the magnitude of G(w). (Not necessarily the Bode plot.) (e) For what frequency range can you use this sensor? x(t) R k с ġ(t) v(t) →f(t) Figure 1: A…

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
