FE Exam Review: Chemical Reactions Section (2022)

October 5, 2022 by Anthony Fasano, P.E. Leave a Comment

In this article (and video above), to help you prepare for the FE exam, we calculate the concentration of a metal compound Hg²⁺. This problem type may be found in the Chemistry and Biology or Chemical Reactions section of the FE Exam, and was created and solved by Engineer in training, Enrique Ivers, LEED Green Associate.

Question:

The Chloride (Cl^–) concentration in a lake is found to be 2.5 x 10^-2. The HgCl₂ (aq) concentration is found to be 5 x 10^-7M. The following chemical equations and equilibrium constants apply:

The concentration of Hg²⁺ is most nearly:

Calculating the Maximum Compression of a Loaded Spring: FE Exam Review

June 1, 2022 by Anthony Fasano, P.E. Leave a Comment

In this article, (and video above), we calculate the compression of a loaded spring to give you a better understanding of what you can expect during the exam. This week’s problem was created and solved by Enrique Ivers, an Engineer in Training.

Question:

A disk with a mass of 1kg, a diameter of 10cm, and a width of 5cm is placed on the edge at the top of an inclined ramp 1m high. The ramp is inclined at 15°. At the bottom of the ramp is a spring whose spring constant is 2,000 N/m. The disk rolls down the ramp and compresses the spring while coming to a complete stop. What is the maximum compression of the loaded spring?

In this article, (and video above), we calculate the velocity of a falling ball. A question on this topic would typically be found in the Dynamics section of the FE Exam and therefore will give you a better understanding of what you can expect during the exam. This week’s problem was created and solved by Enrique Ivers, an Engineer in Training.

Question:

The velocity (in m/s) of a falling ball is described by the equation:

What is the acceleration at time t=2s?

FE Exam Review: Surface Water Resources and Hydrology – Runoff Calculations

September 21, 2021 by Anthony Fasano, P.E. Leave a Comment

In this article (and video above), I solve a new surface water resources and hydrology question by calculating the runoff volume, similar to what you may encounter on the FE exam.

Question:

A 53-acre watershed (curve number = 79) receives 122 mm of precipitation. The runoff volume (ac-ft) is most nearly:

4.11
11.62
18.15
4,615

FE Exams In 2021 – New Changes

April 20, 2021 by Anthony Fasano, P.E. Leave a Comment

In this week’s Pass the FE Exam article (and video above), I am going to provide you with a COVID-19 update on the FE Exams in 2021, and talk about what you need to know if you are planning or have already booked your FE Exam.

It is likely for you to have questions about the status of your FE Exams in 2021, like, what is the status, will it require scheduling new exam appointments at this time? The status of Pearson’s global test delivery is changing rapidly due to the spread of COVID-19.

The Pearson VUE-owned test centers are continuing to monitor the situation and make decisions about test center operations in accordance with government and local authorities.

When Is the Right Time To Take the FE Exam?

December 22, 2020 by Anthony Fasano, P.E. Leave a Comment

Should you take the FE Exam after gaining some real engineering experience OR should you take it while still in college? While every student is different, this is a very important decision. In this week’s Pass the FE Exam post, I interview Justin Edenbaum, a licensed Professional Engineer, once again to get his insights on how to decide exactly when to take the FE exam. Justin has been practicing successfully for a while now and he will share his perspective.

Firstly, let me remind you that the FE EXAM or fundamentals of engineering – is the first step to getting your professional engineering license, and through the videos on this channel, including this one, you will learn not only how to properly prepare for the exam, but how to ensure you PASS THE FE EXAM!
