A ball bearing rotating at 1250 RPM is required to last for 2500 hrs with 90 percent reliability. It must carry a radial load of 400 lb. What would be the minimum acceptable catalog rating for this bearing (Clo value in lb)?Repeat the previous problem but now insist that the reliability should be 98 percent. Use the Weibull parameters. Do you expect to obtain a larger or smaller value for C10 as compared to the result in the previous problem?

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
