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?

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
