A fully loaded wheeled scraper (Model #: 615C) must travel down a 3% slope on an unmaintained hard road (tire penetration is 5 inches and the coefficient of traction is estimated to be 0.45 when traveling downhill, tire penetration is 3 inches and the coefficient of traction is estimated to be 0.45 when traveling uphill), and then return to the same location. Only the front tires of this scraper are powered, and you can obtain the following information from the manufacturer's data. Empty vehicle weight: 97,000 lb; Fully loaded vehicle weight: 172,000 lb; When empty, 37% of the weight on the rear tires, 63% on the front tires; When fully loaded, 50% of the weight on the rear tires, 50% on the front tires; What is the total resistance force when traveling downhil wth y loeded? Select one: O a. 11,180 lbs. o b. 12,125 lbs. OC. 21,500 Ibs. n d. 15.289 lbs.

Introduction to Engineering Design

Students are often confused with engineering and design. The term engineering design has two words with different meanings, engineering, and design. The term engineering implies applications of laws and principles of science to design and analyze physical structures and components. In civil engineering, students apply the concept of physics and chemistry to design and build structures and buildings. In engineering disciplines, the term design means determining the dimensions, loads, and associated influences on the component due to the applied loads such as stresses and deformations. The estimation of such parameters is crucial to make the component or structure foolproof.
