A new machine tool is being purchased for $25,000 and is expected to have a zero- salvage value at the end of its 5-year useful life. Compute its DDB deprecation schedule. Assume any remaining deprecation is claimed in the last year. What is the sum? A O $21.160 O $31.760 O $32.760 $21.760 « Previous

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
