What Is the BMCT?

The BMCT, or Bennett mechanical test Comprehension Test, is a mechanical reasoning assessment used to evaluate how well candidates understand basic mechanical principles.

It is commonly used for technical, mechanical, maintenance, industrial and skilled-trades roles.

BMCT-style questions often show a diagram or describe a simple mechanical situation. You must decide what will happen based on physical principles.

Section 1: Levers and Torque

Question 1: Longer Lever

A worker uses a long pry bar instead of a short pry bar to lift a heavy object. Why does the longer pry bar help?

  • A. It increases mechanical advantage
  • B. It reduces the object’s weight
  • C. It removes gravity
  • D. It eliminates all friction

Answer and Explanation

Correct answer: A. It increases mechanical advantage

A longer lever increases the distance from the fulcrum to the effort point.

Key rule:

Longer effort arm = less effort needed

The object does not become lighter. The tool makes the load easier to move.

Question 2: Fulcrum Close to Load

A load is placed close to the fulcrum, and effort is applied far from the fulcrum. What happens?

  • A. Less effort is needed
  • B. More effort is needed
  • C. The lever stops working
  • D. The load becomes weightless

Answer and Explanation

Correct answer: A. Less effort is needed

A short load arm and long effort arm create more mechanical advantage.

Key rule:

Load closer to fulcrum = easier to move
Effort farther from fulcrum = easier to move

Question 3: Torque

A longer wrench makes it easier to loosen a tight bolt because it:

  • A. Increases torque
  • B. Decreases the bolt’s mass
  • C. Removes the threads
  • D. Makes the bolt weightless

Answer and Explanation

Correct answer: A. Increases torque

Torque is turning force.

Torque = Force × Distance from pivot

A longer wrench increases the distance from the pivot, so the same force creates more torque.

Question 4: Lever Balance

A 100-pound load is 2 feet from the fulcrum. How much effort is needed 4 feet from the fulcrum to balance it?

  • A. 25 pounds
  • B. 50 pounds
  • C. 100 pounds
  • D. 200 pounds

Answer and Explanation

Correct answer: B. 50 pounds

Use the lever formula:

Effort × Effort Arm = Load × Load Arm
Effort × 4 = 100 × 2
Effort × 4 = 200
Effort = 50

Levers Questions

Section 2: Pulleys

Question 5: Fixed Pulley

What is the main purpose of a single fixed pulley?

  • A. It changes the direction of force
  • B. It removes all weight from the load
  • C. It doubles the load
  • D. It eliminates all rope tension

Answer and Explanation

Correct answer: A. It changes the direction of force

A fixed pulley lets a person pull in one direction while the load moves in another direction.

A single fixed pulley does not usually reduce effort by itself.

Question 6: Movable Pulley

A movable pulley is attached to the load. What is its usual advantage?

  • A. It can reduce the effort needed
  • B. It makes the load heavier
  • C. It removes the need for rope
  • D. It creates electrical current

Answer and Explanation

Correct answer: A. It can reduce the effort needed

A movable pulley can reduce effort because the load is supported by more than one rope segment.

Question 7: Rope Segments

A 120-pound load is supported by three rope segments. Ignoring friction, about how much effort is needed?

  • A. 30 pounds
  • B. 40 pounds
  • C. 60 pounds
  • D. 120 pounds

Answer and Explanation

Correct answer: B. 40 pounds

Use:

Effort = Load ÷ Supporting rope segments
Effort = 120 ÷ 3
Effort = 40 pounds

Question 8: Pulley Trade-Off

A pulley system reduces the effort needed to lift a load. What is the usual trade-off?

  • A. More rope must be pulled
  • B. The load disappears
  • C. The rope has no tension
  • D. Gravity stops working

Answer and Explanation

Correct answer: A. More rope must be pulled

Mechanical advantage trades force for distance.

Less effort usually means pulling more rope.

  • A. Clockwise
  • B. Counterclockwise
  • C. It cannot turn
  • D. It turns only halfway

Answer and Explanation

Correct answer: A. Clockwise

  • A. Clockwise
  • B. Counterclockwise
  • C. It does not move

If the same force is applied over a smaller area, pressure:

  • A. Increases
  • B. Decreases
  • C. Becomes zero
  • D. Turns into speed

Answer and Explanation

Correct answer: A. Increases

Use:

Pressure = Force ÷ Area

A smaller area means higher pressure if force stays the same.

Question 19: Ramp

A ramp makes it easier to move a heavy object upward because it:

  • A. Reduces the force needed by increasing the distance moved
  • B. Removes the object’s weight
  • C. Eliminates gravity
  • D. Removes all work

Answer and Explanation

Correct answer: A. Reduces the force needed by increasing the distance moved

A ramp trades distance for force.

Less force is needed, but the object moves along a longer path.
