Two students, named Lenlen and Ferdie were asked by their teacher Juan to carry two boxes across an 8-m, simply-supported beam. Ferdie, having a big crush on Lenlen, suggested to carry the heavier box. Lenlen agreed but proposed that they stay 1-m apart, due to social distancing. If the two boxes weighs 20kN and 15kN, what is the maximum vertical reaction in the support that they could make if Lenlen is ahead of Ferdie?

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.
