MTE PRACTICE EXAM QUESTIONS
AND ANSWERS
Wire thickness is measured in gauges. The smaller the wire gauge number, the -
Answer- Thicker the wire
The most accurate means of checking coupling alignment is with a - Answer- Dial
indicator
When too much grease is added to a bearing without a relief valve, the bearing will -
Answer- Get hot
The reason oxygen gauges read "use no oil" is because - Answer- Oil and oxygen make
an explosive mixture
Electrical contacts in a thermostat must be small and therefore cannot handle the
supply of current to a motor. The heavier current would be controlled through a -
Answer- Relay
What is the purpose of connecting a diode across a DC-operated rely coil? - Answer- To
dissipate inductive voltage
To represent a varying DC voltage from 0 to 7 volts on LED display, one of the main
components would be - Answer- A A/D converter
In digital electronics, the input of an AND gate will be either logic state "1" or "0". If "DC
positive" logic is used for the logic states, what voltage would you expect to read on an
input that is logic state "1" in a 5VDC system - Answer- +5 VDC
In digital electronics, the input of an AND gate will be either logic state "1" or "0". If "DC
negative" logic is used for the logic states, what voltage would you expect to read on an
input that is logic state "1" in a +/- 5VDC system - Answer- -5 VDC
The definition of a computer language is a - Answer- Set of instructions understood by a
computer
ROM is - Answer- Read Only Memory
RAM is - Answer- Random Access Memory
