Unformatted text preview: \‘l o FP'PPE" COE 2001 — Test 3 — Spring 2007 Name: K 9/ PLEASE NOTE: 1. If axes are specified for a given problem, you are to use them. Do not change them in any way or you get a 0 (zero) to that question. Show all work. If you make an assumption, state it clearly. Provide units with your answers, and box them. Use the back of the equation sheet as scrap paper if needed. The “lb” unit means “lb-force” in this test, NOT “lb—mass” (i.e. do NOT multiply by gravity to get a force!). Define clearly any new variable you introduce in a problem based on the givens. Pb. I (50 pts) — 3 small blocks are arranged as drawn below. The weights of block 1, 2, 3 are respectively 50 N, 30 N and 10 N. The pulley is massless and frictionless, and pinned at its center. The coefficient of friction between block 1 and the incline is it, between blocks 2 and 3 it is 60% u, and between block 3 and the flat ground it is 40% u. Disregard tipping. 1. Draw a FBD for each block separately. Specify clearly all forces with names and directions (ie don’t call all friction forces “1‘” and all normal forces “N”!) 2. Draw the axes you will use for each FBD, next to it. 3. What are the 2 possible cases to consider? What condition(s) must hold true for which friction force(s) for either case to work? 4. Calculate the minimum u to keep the system in equilibrium. 5> @@: © abouti‘omdmoifiwu [email protected]/@ SELL/s. l .‘. £:}LNU hzofipwl/ «£3 <O4pklg Pb II (50 pts) — For the beam and loading drawn below, draw its shear force and bending moment diagrams.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
