Question

Find the equivalent resultant force and couple system at points O and D, given:
  F₁ = 45 lbs,   F₂ = 20 lbs,   F₃ = 15 lbs,   L₁ = 8 ft,   L₂ = 6 ft,   L₃ = 5 ft,   x,y,h = 4,3,5, respectively
  F_R =    lbs Φ =   °

  M_O =   lb·ft

  M_D =   lb·ft

Find the equivalent resultant force and couple system at point A. Express your answers as Cartesian vectors. M_B is parallel to the Z-axis and M_C is parallel to the Y-axis. Given forces , moments and lengths are:
  M_B = 140 N·m,   M_C = 100 N·m,   F̄_D = <90, 45, -15> N,   L_X = 7 m,   L_Y = 8 m,   L_Z= 3 m

F̄_R = <   ,     ,     > N

M̄_A = <   ,     ,     > N·m
