Exam 5: Mechanical Engineering Bearings and Gears

Angular contact bearing can take thrust as well as radial loads.

Which of the following cannot tolerate misalignment?

Deep groove ball bearing has immense rigidity.

Which of the following are true about plasticity?

Straight bevel gears are easy to design and manufacture and give reasonably good service with quieter operation.

The main causes of crankshaft vibration are

Camshaft gear is made from which material

A radial bearing supports the load that acts along the axis of the shaft.

If pitch angle is >90, the bevel gear is?

The gears on camshaft and crankshaft are known as

The crankshaft should be inspected for

Modulus of resilience is defined as

In the cam, the distance between the base circle and the nose is called

When the pitch angle is greater than 90?, it is called external bevel gear.

The main reasons for crankshaft wear are

Cylindrical load bearing has lower load capacity as compared to deep groove ball bearing.

Which of the following creates smoother motion?

Cylinder roller creates lesser noise than deep groove ball bearing.

Sliding contact bearings, also called plain bearings have no problem of wear.

In gear boxes and small size motors, rolling contact bearings are used.
