N B. at right angles to the shaft N C. angular with respect to the shaft N D. none of the above 6. In a load, the load is paralel to the shaft. N A. angular N B. thrust N C radial N D. none of the aboveExplanation / Answer
1. A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.It is also used to support the load. Also used in wheels shafts etc.
2.Greatly reduces the effort and energy
3. all of the above.
4.Angular contact ball bearings. Angular contact ballbearings have inner and outer ring raceways that are displaced relative to each other in the direction of thebearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads
5. Bearings support a shaft or housing to permit their free motion about an axis of rotation. Load can be applied tobearings in either of two basic directions. Radial loads act at right angles to the shaft (bearing's axis of rotation).
