5.2. Consider the situation of when two lanes of traffic merge down to one lane, as shown in Figure 5.36. The densities and velocites at the far left and right are known. Assume a steady flow, so the density and velocity do not depend on time, and assume all variables are non-negative. (a) Using the result of Exercise 5.1(a), find an equation that relates the values on the right with those on the left. P2,V2 P3;V3 Figure 5.36 Configuration of roadway used for Problem 5.2.

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.
