You have been assigened as the PM to lead the development of a community dog park. You don't have much experience in this area and you are now tasked with estimating the resources needed. You contact the managers of several dog parks in the region to get their input on how they estimated resources. What technique are you using?

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
