A test sample, with a cross-sectional area of 0.325 in2 and a 2.25” length, is pulled apart in a tensile test machine. The figure below shows the resulting Stress-Strain diagram. Use the information in the diagram to find the information below.

Calculate the modulus of elasticity (E) for this material using YP data:

An engine, weighing 3000 n, is supported on a pedestal mount. it has been observed that the engine induces vibration into the surrounding area through its pedestal at the maximum operating speed. determine the stiffness of the dynamic vibration absorber spring in (n/m) that will reduce the vibration when mounted on the pedestal. the magnitude of the exciting force is 250 n, and the amplitude of motion of the auxiliary mass is to be limited to 2 mm note: in this question type-in right numbers, no decimals, no fractions, no unit. approximate to right number if needed
