Ohio Industrial Maintenance Technician Practice Exam Questions And Correct Answers (Verified Answers) Plus Rationales 2025|2026 Q&A | Instant Download Pdf

• Which tool is best for measuring the outside diameter of a shaft?
• Tape measure
• Micrometer
• Feeler gauge
• Protractor

Rationale: A micrometer is designed for precise measurement of

small external dimensions.

• Which device converts electrical energy into mechanical rotational

energy?

• Transformer 1 / 3

• Motor
• Relay
• Capacitor

Rationale: Motors convert electrical power to rotational or linear

mechanical movement.

3. Lockout/Tagout (LOTO) procedures are used primarily to:

• Improve machine speed
• Prevent accidental energy release
• Control electrical billing
• Lubricate machinery

Rationale: LOTO procedures ensure hazardous energy is isolated

before servicing.

4. A multimeter set to measure continuity will:

• Measure voltage
• Measure frequency
• Check if there is a complete circuit
• Measure resistance accurately

Rationale: Continuity setting tests whether electrical current can

flow.

5. Bearings are used to:

• Restrict rotation
• Increase friction
• Reduce friction between moving parts 2 / 3

• Seal hydraulic systems

Rationale: Bearings support motion while minimizing friction.

6. The unit of electrical resistance is:

• Watt
• Ohm
• Volt
• Ampere

Rationale: Resistance is measured in ohms.

7. A hydraulic system uses:

• Electricity
• Steam pressure
• Pressurized fluid
• Vacuum pressure

Rationale: Hydraulics involve the use of incompressible fluids to

transfer force.

8. A V-belt that is too loose will:

• Increase power transmission
• Slip and reduce efficiency
• Cause overload protection to trip
• Increase belt life significantly

Rationale: Loose belts slip and reduce torque transfer.

9. The primary function of a fuse is to:

• Step down voltage
• / 3
