Conditions of equilibrium

More lifting You exert a 630-N force on rope 2 in the previous problem (Figure P7.13). Write the two equations (x and y) for the first condition of equilibrium using the pulley as the object of interest for a force diagram. Calculate θ₁ and θ₂. You may need to use the identity (sin θ )² + (cos θ )² = 1.
