| contd :- -2- exact frequency. This was approximately twice/sec. throughout the test, or about 1/4 the rate of shaft revolution. It will be observed that at the maximum load, the bearings were subjected to a unit pressure varying from approximately zero to 1500 lbs/sq.in. twice per revolution. Tests of this nature are somewhat limited by the rigidity of the rig. Hs{Lord Ernest Hives - Chair}/W.A.Robotham. | ||
