Mechanical Fitter Interview Questions and Answers for Freshers

There are several types of gears used in mechanical systems.

• Spur gears: used to transmit motion between parallel shafts

• Helical gears: similar to spur gears but with angled teeth for smoother operation

• Bevel gears: used to transmit motion between intersecting shafts

• Worm gears: used for high reduction ratios and self-locking capabilities

• Planetary gears: used in gearboxes to achieve different gear ratios

• Rack and pinion gears: convert rotational motion into linear motion

• Internal g...read more

A bearing is a machine element that constrains relative motion to only the desired motion and reduces friction between moving parts.

• Bearings are used to support rotating shafts and reduce friction between two moving parts.

• There are several types of bearings such as ball bearings, roller bearings, and plain bearings.

• Ball bearings are the most common type of bearing and are used in applications such as electric motors and automotive wheels.

• Roller bearings are used in heavy-duty...read more

A vernier caliper typically has two scales - the main scale and the vernier scale.

• A vernier caliper usually has a count of 0 to 150 on the main scale.

• The vernier scale has divisions that allow for more precise measurements.

• The count on the vernier scale can range from 0 to 9, depending on the caliper's accuracy.

• By aligning the zero on the vernier scale with the main scale, measurements can be taken accurately.
