What is the relation between temperature and strain rate? The graph below shows the effect of temperature on mechanical properties of a carbon steel. Most materials display similar temperature sensitivity for elastic modulus, yield strength, ultimate strength, and ductility. As temperature increase tensile strength, elastic modulus and yield strength of a material tends to decrease….
Vehicle Design and Packaging We are working on redesigning the current generation Toyota Sequoia. The Toyota Sequoia is classified as a sport utility vehicle (SUV). An SUV is a combination of a passenger car with the features of an off-road vehicle. In the US, SUVs are categorized as “light trucks”, as a result, regulations on…

Have you ever wondered why some cars are faster and more efficient than others? Well, it all comes down to something called automotive aerodynamics. The field of automotive aerodynamics involves examining the airflow around a vehicle. The goal is to diminish drag and wind noise and avoid unintended lift forces contributing to aerodynamic instability, particularly…
The automotive body structure is one the main and most important components of a modern automobile. This system serves as the cohesive link for all other subsystems. It accommodates the drivetrain and primarily providing support and protection for passengers and cargo. A robust body structure is imperative to withstand loads, and pressure, and effectively unify…
Background of Market Segment and Benchmark Vehicles: The vehicle segment which was selected to review during this project was the two-seater luxury sports car. This vehicle is usually purchased by people who are well off financially and are over the age of 50. On average the household income of an individual who is purchasing a…
Have you ever wondered how an automotive suspension system is designed? From ATVs (all-terrain vehicles) to locomotives to modern passenger automobiles most types of vehicles that move people from one place to another rely on a suspension system to improve ride quality and comfort. There are a few common types of automotive suspension systems such…
The expansion plans of Acme Granite, Stone & Brick call for the company to add capacity for a new product in 5 years. The company wants to have $360,000 available before it announces the product. If the company sets aside $55,000 now and $90,000 in year 2, what uniform annual amount will it have to…
For the cash flows below, find the value of x that makes the equivalent annual worth in years 1 through 7 equal to $300 per year. Use an interest rate of 10% per year. Show solutions ( a ) by hand and ( b ) using the Goal Seek tool. Sample problems and notes are…
Costs associated with the manufacture of miniature high-sensitivity piezoresistive pressure transducers are $73,000 per year. A clever industrial engineer found that by spending $16,000 now to reconfigure the production line and reprogram two of the robotic arms, the cost will go down to $58,000 next year and $52,000 in years 2 through 5. Using an…
