An aluminum alloy with a yield strength of 350 MPa and a tensile strength of450MPaexhibits a Basquin's Law of σarNf0.1=750MPa. If the alloy is subjected to zero-to-tension fatigue loading, with σmax= 250 MPa, in how many cycles will the alloy fail?(2.3 x 106cycles)After 1.0 x 106cycles at this loading, it is decided that the lifetime needs to be extended by an additional 4.0 x 106cycles in "zero-to-tension" loading. What is the new maximum stress that can be appliedin zero-to-tension loading?(115MPa)

Aheavily insulated piston-cylinder device contains 0.02 m3 of steam at 300 kpa and 200 °c. 1.2 mpa. d this process. team is now compressed in a reversible manner to a pressure of etermine the entropy change and the work done on the steam during this process

What is creep? what is stress relaxation?

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
