Ramsay Test Mechanical Maintenance 1

Question 1

What type of maintenance is performed on a scheduled basis regardless of equipment condition?

Accepted Answer

Preventive maintenance

Answer

Corrective maintenance

Answer

Predictive maintenance

Answer

Breakdown maintenance

Question 2

What does vibration analysis in predictive maintenance primarily detect?

Accepted Answer

Imbalance, misalignment, bearing wear, and looseness in rotating machinery

Answer

Oil contamination and viscosity changes

Answer

Electrical insulation breakdown

Answer

Corrosion on equipment surfaces

Question 3

A shaft coupling is misaligned. Which type of coupling can best accommodate angular misalignment?

Accepted Answer

Flexible jaw coupling

Answer

Rigid sleeve coupling

Answer

Flange coupling

Answer

Compression coupling

Question 4

What is the correct method for installing a bearing onto a shaft using the inner ring press-fit method?

Accepted Answer

Apply force only to the inner ring using a bearing installation tool or press

Answer

Drive the bearing on by striking the outer ring with a hammer

Answer

Heat the bearing and drop it on the shaft

Answer

Apply force evenly to both inner and outer rings simultaneously

Question 5

Which lubrication method is best suited for high-speed, lightly loaded bearings?

Accepted Answer

Oil mist or oil bath lubrication

Answer

Heavy grease packing

Answer

Solid lubricant (dry film)

Answer

No lubrication

Question 6

What is the primary function of a V-belt drive in mechanical power transmission?

Accepted Answer

To transmit power between shafts while allowing for speed ratio changes and absorbing shock

Answer

To provide rigid, zero-slip power transmission

Answer

To transmit power only between parallel shafts at fixed ratios

Answer

To convert rotary motion to linear motion

Question 7

When replacing a hydraulic seal, why is it critical to install the seal in the correct orientation?

Accepted Answer

Seals have a directional lip that must face the pressure side to function properly

Answer

Orientation affects only cosmetic appearance

Answer

All seals are symmetrical and orientation doesn't matter

Answer

Incorrect orientation only affects installation ease

Question 8

What does 'backlash' refer to in a gear set?

Accepted Answer

The small clearance between mating gear teeth allowing for lubrication and thermal expansion

Answer

Reverse rotation of a gear when drive direction changes

Answer

Gear tooth breakage due to overload

Answer

Excessive gear speed causing instability

Question 9

A pump is cavitating. Which of the following conditions is the most likely cause?

Accepted Answer

Insufficient inlet pressure or excessive suction lift causing vapor bubble formation

Answer

Excessive discharge pressure

Answer

Over-lubrication of pump bearings

Answer

Pump running at too low a speed

Question 10

What is the purpose of a torque wrench in mechanical maintenance?

Accepted Answer

To apply a precise, measured amount of torque to fasteners

Answer

To loosen extremely tight fasteners

Answer

To measure shaft torque during operation

Answer

To tighten fasteners as fast as possible
