Honestly, the FE Mechanical Engineering exam is a beast, but maybe not for the reasons you think. Most people walk into the testing center expecting a test of their intelligence. It isn't. Not really. It’s actually a high-speed endurance race designed to see if you can find a specific formula in a 500-page digital PDF while your heart rate is hitting 110 beats per minute.
You’ve spent four (or five, no judgment) years learning how to derive the Navier-Stokes equations from scratch. Then, NCEES hands you 110 questions and 5 hours and 20 minutes to solve them. That’s roughly three minutes per problem. If you’re trying to derive anything on game day, you’ve already lost.

The Fundamentals of Engineering (FE) is the first gatekeeper on the path to becoming a Professional Engineer (PE). It’s computer-based. It’s closed book, except for that NCEES Reference Handbook. And if you haven't opened that Handbook until the week before the exam, you're basically toast.
The NCEES Reference Handbook Is Your Only Friend
Stop buying textbooks. Seriously. When you're sitting for the FE Mechanical Engineering exam, the only thing that matters is how fast you can use the Ctrl+F function.
The Handbook is the literal Bible of this exam. You need to know it so well that you can visualize which side of the page the psychrometric charts are on. Most people make the mistake of studying from their old college notes. Don't do that. Your professor probably used different notation than NCEES. If you get used to $P$ for power but the Handbook uses $\dot{W}$, you’re going to lose ten seconds of "brain-lag" every time you look at a formula. Those seconds add up to failed exams.
Why the Search Bar is a Trap
Newer versions of the Pearson VUE testing software have a searchable PDF, but it’s finicky. If you search for "Stress," you might get 150 hits. You don't have time to click through 150 hits. You need to search for "Principal Stress" or "Mohr’s Circle." Precision matters.
Thermodynamics and Heat Transfer: The Heavy Hitters
Let's look at the breakdown. NCEES actually publishes the exam specifications, and they aren't secret. Thermodynamics usually accounts for about 10 to 15 questions. Heat Transfer is another 9 to 14. Combined, these two subjects can make up nearly a quarter of your total score.
If you can’t quickly solve a Rankine cycle or find the R-value of a composite wall, you’re in trouble. But here’s the kicker: the problems aren't usually "hard" in a theoretical sense. They are "hard" because they include a "trick" unit conversion. You’ll get a mass flow rate in pounds-mass per minute when the formula requires slugs per second.
- Watch your units. I can't stress this enough.
- Get comfortable with the difference between $g_c$ in the US Customary System and the clean, easy $9.81$ in Metric.
- Standardize your workflow for cycle problems.
The "Bread and Butter" Specs
Statics and Dynamics are the foundation. You probably took these sophomore year, which means you’ve forgotten them. You’ll see about 8-12 questions on Statics. Most of them involve 2D or 3D equilibrium. If you can't do a cross-product for a moment calculation in under 60 seconds, practice until you can.
Dynamics is where people start to sweat. Work-energy and impulse-momentum are the big ones here. Most FE Mechanical Engineering exam takers overthink Dynamics. They try to set up complex differential equations. Usually, it’s just a simple conservation of energy problem where $T_1 + V_1 = T_2 + V_2$.
Mechanical Design and Analysis
This section is huge. 10 to 15 questions. It covers everything from bolt joints to gear trains and fatigue. This is where the "Mechanical" part of the FE Mechanical really shines. You need to understand the Goodman criteria and Soderberg lines.

Specifically, look at:
- Springs: Deflection and spring constants in series vs. parallel.
- Bearings: Life expectancy calculations ($L_{10}$).
- Gears: Velocity ratios and torque.
If you’re using the Lindeburg FE Mechanical Review Manual, you’ll notice the problems in that book are way harder than the actual exam. That’s intentional. It’s like training with weights on your ankles. Just don’t get discouraged if a Lindeburg problem takes you 20 minutes. On the real test, it’ll be a 3-minute version of that same concept.
Fluid Mechanics: Don't Drown in the Math
Fluid mechanics (9-14 questions) is basically Bernoulli’s equation on repeat. However, the FE loves to throw in head loss. If you see "Darcy-Weisbach," don't panic. Just find the friction factor on the Moody chart.
Wait. The Moody chart.
Have you tried reading a Moody chart on a 20-inch monitor with low resolution? It’s a nightmare. Practice looking at digital versions of the chart. Don't rely on your nice, crisp printed copy. You need to be able to interpolate between those logarithmic lines without losing your mind.
The Strategy Nobody Talks About: The Break
The exam is split into two halves. You get a 25-minute break. Take it. Even if you’re feeling like a genius after the first 55 questions, your brain is essentially a muscle that’s been doing heavy lifting. It needs oxygen and a snack. If you skip the break, you’ll hit a wall around question 85. That’s when you start making "stupid" mistakes, like forgetting to square a radius in a circle area formula.
The Flagging System
The testing interface lets you "flag" questions. Use this religiously.
If a question looks like it will take more than three minutes, flag it and move on.
If it’s a subject you hate (looking at you, Ethics or Materials Science), flag it.
The goal is to bank as many "easy" points as possible in the first two hours. You want to reach the end of the section having answered every question you know how to do. Then, go back to the flagged ones. This prevents a situation where you spend 10 minutes struggling with a Fluid Mechanics problem and never even see the three easy Math questions at the very end.
The Calculator Rule
You can't just bring any calculator. NCEES is strict. Most people use the TI-36X Pro or the Casio FX-115ES Plus.
The TI-36X Pro is arguably the better choice for the FE Mechanical Engineering exam because it handles unit conversions and vector math like a dream. If you aren't using your calculator to solve systems of linear equations, you're wasting time. If you’re manually doing a $3 \times 3$ matrix inversion, stop. Learn the "Matrix" mode on your calculator tonight.
What People Get Wrong About Ethics and Economics
Engineering Economics and Ethics are "easy" points that people leave on the table. You’ll see about 3-5 questions on each.

For Economics, it’s all about the interest tables in the back of the Handbook. "Present Worth," "Future Worth," "Annualized Cost." It’s basically just accounting for the time value of money. Don't miss these.
For Ethics, read the NCEES Model Rules. It’s not about what you think is right; it’s about what the code says. Usually, the answer is "the safety of the public is paramount." If an answer choice involves "notifying the proper authorities," it's probably the right one.
Materials Science and Manufacturing
This is often the "forgotten" section. Phase diagrams, TTT diagrams, and stress-strain curves.
Understand the difference between ductile and brittle fractures. Know how to read a grain size chart. These are often conceptual questions that take 30 seconds. If you know them, you gain time for the harder stuff.
Actual Next Steps to Pass
Stop browsing forums and start doing.
- Download the NCEES Reference Handbook 10.3 (or latest version) immediately. It is free on your MyNCEES account. Use it for every single practice problem you solve from now on.
- Get a TI-36X Pro. Learn the "Solver," "Vector," and "Stat" functions. These will save you 15 minutes of manual calculation over the course of the exam.
- Take a timed practice exam. Not a "sit down for an hour" session. A full, 5-hour, 110-question simulation. You need to feel the fatigue. You need to know what it feels like when your eyes start to blur at question 90.
- Focus on your strengths first. If you’re a Heat Transfer whiz, make sure you never miss a Heat Transfer question. It’s easier to go from 80% to 100% in a strong subject than 20% to 50% in a weak one.
- Master the search terms. Practice finding "Centroids," "Torque," and "Coefficient of Performance" in the Handbook. Don't scroll. Search.
The FE Mechanical Engineering exam has a pass rate that usually hovers around 65% to 75% for first-time takers from ABET-accredited programs. It’s not an impossible hurdle. It’s just a test of your ability to be an engineer under pressure—resourceful, fast, and precise. Forget the complex derivations; embrace the Handbook and the calculator. That's how you get the EIT after your name.
