  2. Problem 4.5.32 • Find • Fx • Fy • Fu • Fv • By • AutoCAD • MATLAB

  3. Problem 4.5.32  AutoCAD • ReCreate File P4_5_32_FULL_scale_1009.dwg

  4. Problem 4.5.32  MATLAB • By Law of Sines • Using MATLAB >> Fu = sind(40)*500/sind(119) Fu = 367.4669 >> Fv = sind(21)*500/sind(119) Fv = 204.8707

  5. Pythagorus Yea or Nay? • Test Pythagorean Theorem on Both Sets Fu = sind(40)*500/sind(119) Fv = sind(21)*500/sind(119) Fx = 500*cosd(38) Fy = 500*sind(38) MagFxy = sqrt(Fx^2+Fy^2) MagFuv = sqrt(Fu^2+Fv^2) Fu = 367.4669 Fv = 204.8707 Fx = 394.0054 Fy = 307.8307 MagFxy = 500 MagFuv = 420.7184 • Since the uv Basis is NOT OrthoGonal, then Pythagorus does NOT hold
