If i can live with a 3% probability of failure, select a ball bearing design (independent of shaft diameter that will carry a 120 ib load at 3000 rpm. how long can i expect the selected bearing to perform satisfactorily? how long can i expect it to last if i run it at the static load rating for the bearing?

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Ahe-xe mixture containing a 0.75 mole fraction of helium is used for cooling electronics in an avionics application. at a temperature of 300 k and atmospheric pressure, calculate the mass fraction of helium and the mass density, molar concentration and molecular weight of the mixture. if the cooling capacity is 10 l, what is the mass of the coolant?
