Engineering is a fiercely competitive and highly rewarding field, but how does engineering economics play into this and why is it important for students and recent graduates to fully understand this practical and performance-enhancing skill? March 2, 2024 by Kazu Fujimoto What Is Economic Engineering? If your aim is to eventually secure a job in the … Read more
A Stress Strain Curve of a material represents the physical values of stress and strain from material testing. The stress strain curve of a material gives us key data in which we use to determine if the material we are selecting will work. To get a real stress strain curve of a material specimen, we … Read more
The strain formula is ε = δ / L Represented by the following variables: March 2, 2024 by Kazu Fujimoto If we take into a account an axially loaded beam shown in the figure, where the small line element AB = ∆x suffers a deformation to become the element A’B’ The point A has been displaced by … Read more
The formula for normal stress is σ = P/A With the following variables: In the industry, it will be important to know how to quickly calculate normal stress in mechanical design applications. This will be important in determining whether or not an application will be safe upon it’s operating conditions. Although Finite Element Analysis is … Read more
Mohr’s circle represents a graphic technique which transforms stress from one plane to another. This graphical technique is what leads to the determining of maximum normal and shear stresses. March 2, 2024 by Kazu Fujimoto In the figure above, the right hand figure shows the circle relative to what the normal stress values are. The … Read more
Strain in engineering is really important to understand, so you really need to know what it is as an engineer. This is information that customers want for the design of structures and mechanisms upon loading. Strain is a dimensionless parameter that describes elongation over the total length of an object. What strain tells us is … Read more
If you’re an engineer you absolutely need to know what is stress in engineering. Stress is a fundamental phenomenon that many mechanical, electrical, and civil systems are subject to. As an engineer you will be designing systems, and these systems will undergo stress. It is your job as an engineer to make sure that the … Read more
A goodman diagram is widely used in engineering fatigue applications. Why do we care so much about a goodman diagram? A goodman diagram will be able to tell us whether a part can be subject to finite or infinite cycles. Fatigue in engineering is a very interesting concept. Parts can be subject to stresses much … Read more
Don’t understand basic strength of materials interview questions? You won’t get the job. Knowing basic strength of materials is necessary for both for a job interview and for general knowledge as an engineer. You will not provide value if you don’t understand the basics of strength of materials. Engineering classes go very in depth, but … Read more
One of the very first things you need to do as an engineering student is learn how to pass statics. Statics is a very fundamental engineering course that you need to know how to pass or otherwise you will struggle in later courses. Although Statics is a difficult class, it can be broken down into … Read more
