Problem 3-1 Determine the magnitudes of F1 and F2 so that the particle is in equilibrium. Given: F = 500 N
θ 1 = 45 deg θ 2 = 30deg
Solution: Initial Guesses F 1 = 1N Given
+ → ΣFx = 0; +
F 2 = 1N
F 1 cos ( θ 1 ) + F2 cos ( θ 2 ) ? F = 0 F 1 sin ( θ 1 ) ? F 2 sin ( θ 2 ) = 0
↑ ΣFy = 0;
? F1 ? ? ? = Find ( F1 , F2) ? F2 ?
? F1 ? ? 259 ? ? ?=? ?N ? F2 ? ? 366 ?
Problem 3-2 Determine the magnitude and direction θ of F so that the particle is in equilibrium. Units Used: kN = 10 N Given: F 1 = 7 kN F 2 = 3 kN c = 4 d = 3
