Acylindrical part of diameter d is loaded by an axial force p. this causes a stress of pia, where a= 10-14. if the load is known with an uncertainty of 112 percent, the diameter is known within 14 percent (tolerances), and the stress that causes failure (strength) is known within t19 percent, determine the minimum design factor that will guarantee that the part will not fail.

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
