The ball-outer-race contact of a ball bearing has a 17-mm ball diameter, an 8.84-mm outer-race groove radius, and a 44.52-mm radius from the bearing axis to the bottom of the groove. The load on the most highly loaded ball is 10,000 N. Calculate the dimensions of the contact ellipse and the maximum deformation at the center of the contact. The race and the ball are made of steel. Ans. Dy = 6.935 mm, Dx = 0.9973 mm.

A 6.0-mm-diameter copper ball is charged to 80 nC . What fraction of its electrons have been removed? The density of copper is 8900 kg/m3
2a) A steel ball bearing is to be manufactured with a diameter of 2 cm. The manufacturing process has a tolerance of £.1 mm in the diameter. Given that the density of steel is about 7.85 cg , estimate the propagated error in the mass of the ball bearing. cm3 , Notel: Use differentials to solve this problem. You must use correct notation. Note 2: mass=volume x density b) Is the error found in part a) significant? Ta get a...
A perfectly spherical iron ball bearing weighs 25.35 grams. Derive the diameter of the ball bearing assuming an iron atom has an effective radius of 0.124nm and iron is BCC at room temperature. The answer should be in cm with 2 decimals of accuracy.
A journal bearing has a shaft diameter of 75.00-mm with a unilateral tolerance of -0.02 mm. The bushing bore has a diameter of 75.10 mm with a unilateral tolerance of 0.06 mm. The bushing is 36 mm long and supports a load of 2 kN. The journal speed is 720 rpm. For the minimum clearance assembly find the minimum film thickness and the maximum lubricant pressure for SAE 20 and SAE 40 lubricants operating at an average film temperature of...
