ENG 6 Lecture Notes - Lecture 2: Modulus Guitars, Problem Solving, Matlab
Document Summary
Problems will involve environmental issues/sustainability: water supply, food production, energy production and consumption, waste and pollution management, housing and shelter, transportation. Solar powered electric vehicle charge station: addresses 3 issues: shelter, energy production, pollution management. Engineers need quantitative, detailed, rigorous methodology: also creativity, judgment, teamwork, tools, using hardware + software leads to best solutions. Ex. provide electricity for a building using solar power. Transform vague problem statement into specifications: feasibility analysis. Preliminary calculations-is it feasible: sanity check. Can it be done: design and verify. Can be done with software like matlab, hardware like microcontrollers: refine and iterate. Geometry: sin(pi) % sine of pi radians, cos(pi/2) % cosine of pi/2, asin(1) % arcsine of 1, sind(75) % sine of 75 degrees. Integer functions fix(5. 3) % round towards 0; ans=5: round(5. 3) % round towards nearest integer; ans = 5, ceil(5. 3) % round towards +inf; ans = 6 floor(5. 3) % round towards inf; ans = 5.
