MSP Group Mechanical Fitter Interview Questions and Answers

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.

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 gea...read more
