Show transcribed image text A printed circuit board of mass 1 kg is supported using an undamped isolator. During shipping the base is subjected to a harmonic disturbance of 2 mm amplitude at a frequency of 12 Hz. Determine the stiffness of the isolator so that no more than 5% of the base motion is transmitted to the circuit board.

A cylindrical specimen of some metal alloy 8.7 mm in diameter is stressed in tension. A force of 1390 N produces an elastic reduction in specimen diameter of 0.0041 mm. Calculate the elastic modulus (in GPa) of this material if its Poisson's ratio is..
a simple steam power system has a turbine inlet state of 6.0 mpa and 540 0c and an exhaust pressure 0.008 mpa. the
For some metal alloy, a true stress of 345 MPa (50040 psi) produces a plastic true strain of 0.02. How much will a specimen of this material elongate when a true stress of 417 MPa (60480 psi) is applied if the original length is 470 mm (18.50 in.)? A..
