Question 1
Two gears, Gear A and Gear B, are meshed directly together. If Gear A is turning in a
clockwise direction, in which direction is Gear B turning?
A) Clockwise
B) Counter-clockwise
C) It remains stationary
D) It alternates directions
Answer: B) Counter-clockwise
Rationale: When two external gears mesh directly together, they always rotate in
opposite directions. Since Gear A turns clockwise, it forces Gear B to rotate counter-
clockwise.
Question 2
A construction worker uses a standard wheelbarrow to transport heavy bricks. A
wheelbarrow is an example of which class of lever?
A) First-class lever
B) Second-class lever
C) Third-class lever
D) Fourth-class lever
,Answer: B) Second-class lever
Rationale: In a second-class lever, the load is located between the fulcrum and the
effort force. For a wheelbarrow, the front wheel acts as the fulcrum, the heavy bucket
holding the bricks is the load, and the handles are where the effort force is applied.
Question 3
A heavy crate is suspended from a ceiling by a single rope threaded through a single
fixed pulley. If the crate weighs 100 pounds, how much effort force must a firefighter
exert on the rope to hold the crate steady in mid-air?
A) 50 pounds
B) 100 pounds
C) 150 pounds
D) 200 pounds
Answer: B) 100 pounds
Rationale: A single fixed pulley provides zero mechanical advantage. It only changes
the direction of the force required to move the load. Therefore, the effort force matches
the load weight exactly (100 pounds).
Question 4
An operational water pipe suddenly narrows to half its original diameter. Assuming the
water pressure driving the flow remains constant, what happens to the velocity (speed)
of the water as it passes through the narrower section of the pipe?
A) The velocity decreases
B) The velocity increases
C) The velocity remains exactly the same
D) The water flow stops completely
Answer: B) The velocity increases
Rationale: According to the principle of fluid continuity, the mass flow rate of an
incompressible fluid must remain constant. When the cross-sectional area of a pipe
decreases, the fluid must speed up (increase velocity) to pass the same volume of
water through the restriction.
,Question 5
A mechanic is trying to loosen a rusted bolt. Which of the following modifications will
provide the greatest increase in torque (turning force) applied to the bolt?
A) Using a shorter wrench handle
B) Applying force closer to the bolt head
C) Using a longer wrench handle
D) Spraying water on the wrench handle
Answer: C) Using a longer wrench handle
Rationale: Torque is calculated by multiplying force by the length of the lever arm
(Torque = Force × Distance). Increasing the length of the handle increases the distance
from the pivot point, maximizing the turning force applied to the bolt.
Question 6
Look at a simple playground see-saw. If a 60-pound child sits 4 feet away from the
center pivot point (fulcrum), how far away from the fulcrum must an 80-pound child sit
on the opposite side to bring the see-saw into perfect balance?
A) 2 feet
B) 3 feet
C) 4 feet
D) 5 feet
Answer: B) 3 feet
Rationale: For a lever to balance, the clockwise torque must equal the counter-
clockwise torque (Weight 1 × Distance 1 = Weight 2 × Distance 2). Calculation: 60 lbs ×
4 ft = 240 ft-lbs. To find the matching distance: 240 ft-lbs / 80 lbs = 3 feet.
Question 7
Three gears are meshed in a straight line: Gear A drives Gear B, and Gear B drives
Gear C. If Gear A rotates clockwise, what is the rotational direction of Gear C?
A) Clockwise
B) Counter-clockwise
C) It does not move
D) It moves backward and forward
, Answer: A) Clockwise
Rationale: In a straight train of interconnected gears, directions alternate with each
mesh. If Gear A is clockwise, Gear B must be counter-clockwise. Because Gear B turns
counter-clockwise, it forces Gear C to rotate clockwise.
Question 8
A mechanical hoist system uses a movable pulley connected directly to a heavy engine
block. If this system creates a mechanical advantage of 2, how much rope must you pull
to raise the engine exactly 3 feet into the air?
A) 1.5 feet
B) 3 feet
C) 6 feet
D) 12 feet
Answer: C) 6 feet
Rationale: Mechanical advantage multiplies force but requires a trade-off in distance. If
a pulley system cuts the force needed in half (Mechanical Advantage = 2), you must pull
twice the distance of rope. Calculation: 3 feet × 2 = 6 feet.
Question 9
A block of ice is dragged up a ramp into the back of a utility truck. A ramp is a classic
example of which simple machine?
A) Wedge
B) Inclined plane
C) Screw
D) First-class lever
Answer: B) Inclined plane
Rationale: An inclined plane is a flat surface tilted at an angle. It allows heavy objects to
be lifted to a higher elevation with less effort force than lifting them straight up vertically.
