1 ME 270 Sprng 2013 Fnal Examnaton Please read and respond to the followng statement, I have not receved unauthorzed ad n the completon of ths exam. Agree Dsagree Sgnature INSTRUCTIONS Begn each problem n the space provded on the examnaton sheets. If addtonal space s requred, use the paper provded to you. Work on one sde of each sheet only, wth only one problem on a sheet. Each problem s worth 20 ponts. Please remember that for you to obtan maxmum credt for a problem, t must be clearly presented,.e. the coordnate system must be clearly dentfed. where approprate, free body dagrams must be drawn. These should be drawn separately from the gven fgures. unts must be clearly stated as part of the answer. you must carefully delneate vector and scalar quanttes. If the soluton does not follow a logcal thought process, t wll be assumed n error. Please crcle your nstructor s name: Nauman Slvers Chagdes Problem 1 Problem 2 Problem 3 Problem 4 Problem 5 Total
