Homework The history of performance automobile design and production has been characterized by trying to get more speed for less power. High power engines are heavy, require more cooling, and consume fuel at a high rate. It is therefore advantageous for a race car to have an aerodynamic body to reduce drag. This assignment will walk you through how to estimate the top speed of a car given that we know the power rating of the engine and a few...

12) There are several types of drag on a car other than air resistance. Effects having to do with the squeezing of the tires (rolling resistance) and frictional forces in the drivetrain (the system that transfers energy from the engine to the rotation of the wheels) also must be taken into account. Engineers use the following equation to model the total force due to these different effects Fdrag=A+Bv+Cv^2 For a Camry, these coefficients are estimated to be A=117.130 N, B=1.800...

Design a "bungee jump" apparatus for adults. A bungee jumper falls from a high platform with two elastic cords tied to the ankles. The jumper falls freely for a while, with the cords slack. Then the jumper falls an additional distance with the cords increasingly tense. Assume that you have cords that are 12 m long, and that the cords stretch in the jump an additional 19 m for a jumper whose mass is 120 kg, the heaviest adult you...

      MK Restaurant: Branding of Thai-Style Hotpot The restaurant industry is one of the most competitive in Thailand. With a large number of players ranging from restaurants in five-star hotels, global fast-food chains to small stalls along the streets and everything in between, the Thais are spoiled for choice. In addition, as the world becomes globalized, consumers are familiar with international dishes and would not hesitate to try new offerings from the other side of the globe. As a...
