ME1300 – Statics Tutorial 2 1. A position vector extends from the origin to point A(2 m,3 m,6 m). Determine the angles γ β α , , which the tail of the vector makes with the x,y,z axes, respectively. Answer: o o o 0 . 31 , 6 . 64 , 4 . 73 = = = 2. Express the position vector r in Cartesian vector form; then determine its magnitude and coordinate direction angles. Answer: r = 3 i +6 j -2 k ; r = 7 m ; α = 64.6, β = 31.0, γ = 106.6 3. The hinged plate is supported by the cord AB. If the force in the cord is F=340N, express this force, directed from A toward B as a Cartesian vector. What is the length of the cord? Answer: F = {-154.9 i -193.62 j + 232.35 k } N ; 4.39 m
