Polluted water can create major issues for humans and the natural world. Therefore, monitoring water quality is crucial to identify potential environmental problems and to develop effective preventative strategies and appropriate water treatment techniques. As we prepare for the FE Civil or FE Environmental Exam, we must understand the main indicators of water quality and…
One of the most fundamental concepts in all of mechanics is the free-body diagram (FBD) and learning how to draw the FBD correctly can be a fairly challenging. Drawing the correct FBD is a crucial first step when analyzing an FE Exam Statics problem. Watch the video below to learn how to draw the correct…
Just like how there are ethical guidelines used by practitioners of medicine, science, finance, real-estate and law, an engineering professional is expected to obey these “ethical codes” in their respective practices. Modern codes for the practice of engineering place paramount priority on obligations to the public. There are several codes of ethics for engineers, in…
For the FE exam or PE exam, before solving concrete mix design questions, we must understand the concept of how a mix design is largely dependent on the mass and volume of the aggregate particles. These aggerates with the binder must be proportioned in a way that will achieve desired concrete properties. So how do…
When we look at a beam carrying loads transverse to its axis will experienceshearing forces, denoted by V. In the analysis of beams, it is typical to calculate the variation in shearing force across the entire length of the beam by drawing the shear force diagram. With the shearing force known, we can calculate…
For the FE exam, visualizing different inflow and outflow parameters that contribute to the change in storage of a small watershed, lake, river, stream or any other water body is the most important step we need to understand before applying a water budget analysis. The goal of this post is to help us look visualize…
