1. A mechanic uses a hydraulic jack to lift a heavy truck for
maintenance. The mechanic applies a force of 50 Newtons to a
small piston with an area of 0.01 square meters, which
connects to a larger cylinder with an area of 0.5 square meters
supporting the vehicle. What is the maximum weight the large
cylinder can lift?
A. 1,000 Newtons
B. 2,000 Newtons
C. 2,500 Newtons
D. 5,000 Newtons
Rationale: Pascal's Principle states that pressure applied to an enclosed
fluid is transmitted undiminished throughout the fluid. Pressure is
calculated as Force divided by Area (
𝑃
=𝐹1
/𝐴1
). In this system,
𝑃
=50
/0.01
=5
, ,
000
N/m2
. To find the lifting force of the larger cylinder (
F2cap F sub 2
𝐹2
), multiply this pressure by the larger area (
𝐹2
=𝑃
×𝐴2
). Therefore,
𝐹2
=5
,
000
×0.5

2. Because the commander noticed that several new recruits
were struggling to keep up during the rigorous morning
physical training sessions, she decided to defer the advanced
,obstacle course challenge until the entire platoon achieved a
baseline level of endurance. What is the most precise meaning
of the word "defer" in this context?
A. To cancel permanently
B. To put off to a future time
C. To accelerate the timeline
D. To submit to another's wish
Rationale: In this context, "defer" means to postpone or delay an action
until a certain condition is met. The sentence indicates the challenge is
not canceled permanently, but rather held back until the platoon's
endurance improves.
3. An electronics technician needs to determine the total
resistance in a complex circuit configuration. The circuit
contains a 12-ohm resistor and a 6-ohm resistor connected
strictly in a parallel arrangement, which is then connected in
series with a single 8-ohm resistor. What is the total overall
resistance of this entire circuit?
A. 26 ohms
B. 14 ohms
C. 12 ohms
D. 4 ohms
Rationale: First, calculate the equivalent resistance of the parallel
section using the formula
1
/𝑅𝑝
=1
/𝑅 1
+1
/𝑅 2
. This gives
1
/12
, +1
/6
=1
/12
+2
/12
=3
/12
, so
𝑅𝑝
=12
/3
=4
ohms
. Next, because the 8-ohm resistor is in series with this parallel
combination, simply add their resistances together:
4
ohms
+8
ohms
=12
ohms
.
