A diaphragm pressure transducer uses the deflection of a circular membrane to indicate the pressure. The membrane is composed of a steel alloy with an elastic modulus of E = 30,000,000 psi, Poisson's ratio of µ = 0.33, and density of p = 0.28 Ibm/in³. The diaphragm has a radius of a = 0.625 in. and a thickness of t = 0.125 in. The transducer has a 10 psi maximum reading. a. What is the resonant frequency for the diaphragm? b. Consider frequencies well below resonance. If you would like to know the pressure to within 0.25% of full scale, how accurately must the membrane deflection be measured (in inches)? Neglect the uncertainties in the dimensions and material properties of the diaphragm.

A steel beam (E = 30*10^3 ksi) and an aluminum (E = 10*10^3 ksi) beam are attached to an instrumentation box as shown. Both beams have a thickness of 0.30 inches and a width into the plane of the paper of 1.5 inches. Vibration measurements from the instrumentation box indicate a sinusoidal displacement with a maximum displacement max = 0.20 inches and a minimum displacement min = -0.2 inches. The stress concentration at both fixed supports is negligible. If AlSI cold rolled 1030 steel (Sut =76 ksi) is used, will the steel beam have an infinite fatigue life?
