The spreader beam AB is used to slowly lift the 3000-lb pipe that is centrally located on the straps at C and D. If the beam is a W12 x 45, determine if it can safely support the load. The allowable bending stress is u allow = 22 ksi and the allowable shear stress is Tallow = 12 ksi.
ENGR 121 B Lecture Notes for 9/19/2016 Spencer Kociba Summary of Lecture: beginning to understand the vocabulary and functions in MATLAB and how we will use MATLAB and BlackBoard Learn to turn in assignments, take quizzes, etc. Goal of the course: learn to THINK like a programmer aka step by step problem solving. Problem solving techniques: ● Plan ● Restate the problem ● Divide the problem into steps or subproblems to solve ● Reduce/Simplify the problem (ex. Global scale>local scale) ● Look for similarities to other previously solved problems ○ Emotional attachment/familiarity with an idea or concept improves your memory and ability to recall information when needed ● Experiment ● PERSERVERE ○ Frustration is normal, embrace it and use it to drive yourself to success General Class info: ● Software provided by Drexel (see software.drexel.edu and the syllabus for activation key for FREE MATLAB download) ● Laptop computers needed for every lab ● Quizzes will be done in lab section ● NO LATE ASSIGNMENTS WILL BE ACCEPTED ○ Most assignments you can submit as many times as you want. TAs will take the final submission as your score (usually this will be the successful or most successful attempt) ○ Don’t plagiarize. They’ve got software that can detect it in your wo
