Licensed Mechanical Engineer Reviews a Modified Electric Vehicle – Part 1

2018-03-05T17:14:11+00:00

A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle  Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle.  The company hoped to repurpose a float/SUV that they had used previously in parades.  Our client was requested by the theme park to repurpose the SUV, and perform cosmetic alterations [...]

Comparing Wind Load Calculation Methods

2018-02-21T15:26:59+00:00

Wind Load Calculation Wind Load Calculation is an overview of the force that blowing wind exerts on a tall object.  A number of factors that influence the actual wind load on a real building, include the surrounding terrain, nearby structures,  trees, and typical weather patterns for the area.  Comparing wind load calculations are most complicated . Calculations try to account for as many of these external factors as possible, to the point where the wind load section in American Society for Civil Engineer’s ASCE 7 standard, spans five chapters and over 100 pages. Fig 1: Wind load calculation example structures ASCE 7's Applications Comparing one of ASCE 7’s Applications with the two equations [...]

Window Energy Efficiency: Solar Heat Gain and Visible Transmittance

2018-03-22T15:13:18+00:00

Conduction and Radiation of Thermal Energy In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer.  The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but it is only one piece of the puzzle.  The National Fenestration Research Council (NFRC) mandates a second value alongside U-factor in its certification process, called the Solar Heat Gain Coefficient (SHGC).  SHGC represents the ability of a window to resist heat gain from radiation, like the sunlight in Figure 1.  This is obviously a challenge, given that the entire point [...]

Italian Masters: Leonardo da Vinci – Artist, Engineer, Scientist

2018-02-20T13:14:29+00:00

Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi.  I’ve saved the best for last, however: Leonardo da Vinci.  He is the quintessential renaissance man who fits both our running definition of “Italian Master” as well as being included in the standard list of Masters with Rafael, Donatello and Michelangelo  Leonardo’s incredibly broad array of talents and interests have long been the subjects of movies, books, TV shows, and, of late, video games.  Throughout his life, he had one hand in the arts, ranging from painting, sculpting, music, history, and literature, [...]

Italian Masters: Volta Jump-Starts Electrical Engineering

Italian Masters: Volta Jump-Starts Electrical EngineeringFigure 1: Girolamo Cardano (1501-1576) Welcome back to our series on Italian Masters of math and science.  Last week I wrote about Galileo’s extensive accomplishments both in the field of astronomy and beyond.  This week, I’ll take a look at another renaissance polymath who dabbled in astronomy, along with his work in mathematics, medicine, biology, chemistry, philosophy, and gambling (yes, seriously): Girolamo Cardano.  Cardano is a less well-known figure than Galileo or some of the other scientists I’ve written about who have famous equations or units of measurement named after them, like Volta or Torricelli.  He is regarded as one of the greatest mathematicians of his age, however, and made a great many contributions to science, [...]

Italian Masters: Galileo’s Stellar Science and Engineering

Portrait of Galileo Galilei Justus Sustermans [Public domain], via Wikimedia Commons I’d like to return to our previous series on the Italian Masters, focused not on the usual masters or painting and sculpture but on the masters or science, mathematics, and engineering.  So far in the series I’ve written about the accomplishments of Volta, Cassini, Venturi and Torricelli.  Today, I’d like to look at one of the greats: Galileo Galilei.  Galileo is most famous today for standing up for heliocentrism against the Catholic Church and spending the last years of his life under house arrest as punishment.  However, Galileo didn’t let controversies or confinement stop him, and accomplished a great amount of research in not only [...]

FEA Consulting Part 3: Meshing and Boundary Conditions

2018-03-27T15:27:13+00:00

We'll continue on now with our blog series on finite element analysis (FEA).  After discussing how to best set up a computer-aided design (CAD) model for FEA simulation, in this blog I'll cover the next step: meshing the model and applying boundary conditions.  "Meshing" is the process by which the CAD model is separated into discrete finite elements; it can be done in the same program that runs the FEA numerical simulation later, or it might be performed in a standalone program, depending on your software.  Boundary conditions are the loads (forces, movements, impacts, etc) and constraints that interact to actually cause deformation and stress in each element, and in turn the model as a whole. Mesh Generation The mesh essentially [...]

Italian Masters: Venturi and the Venturi Effect

2017-05-03T14:48:59+00:00

Figure 1: Giovanni Battista Venturi [i] Glew's News is doing a short series highlighting the lives and accomplishments of the Italian Masters of science, engineering, and mathematics.  In the last blog, I wrote about Evangelista Torricelli, a mathematician and physicist from the 17th century.  In this blog, I'm focusing on Giovanni Venturi (Figure 1), an accomplished physicist, hydrodynamicist and engineer. Giovanni Battista Venturi (1746-1822) Giovanni Venturi was born to a wealthy family in Reggio, Italy in 1746.  A talented young student, by the age of 23 the local seminary had already ordained him as a priest and professor.  His talents in mathematics didn’t long escape notice at the nearby University of Modena, which appointed him as a professor of geometry and [...]

Figure 1: Reinforced concrete mesh © Glew Engineering Consulting Welcome back to our blog series on FEA.  In the last blog entry, we introduced some of the fundamental concepts in finite element analysis (FEA).  This entry in the blog series focuses on the initial steps in preparing a computer-aided design (CAD) model ready for use in an FEA program.  Since FEA programs are very sensitive to the data they have to work with, it's important that the CAD models being analyzed are compatible with the analysis methods the FEA program uses. In order to illustrate my points throughout the blog series, I will introduce a recent FEA consulting project that we completed. Modeling Punching Shear in a Concrete Slab We were recently approached by an academic, who was examining [...]
