Given the following second-order transfer functions, find the natural frequency, damping ratio, steady-state output, 2% settling time, peak time, and overshoot percent assuming a step input is applied. a) x + 4x + 40x = (t)b) x + 2x + 24x = (t)c) x + 20x + 100x = (t)

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

When subject to a steady load (within elastic range) over a long period of time, what is the major difference in material behavoir between steel and plastic?

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
