Member BD exerts on member ABC a force P directed along line

Member BD exerts on member ABC a force P directed along line BD. K nowing that P must have a 300-lb horizontal component, determine (a) the magnitude of the force P, (b) its vertical component. 35°

a) Magnitude of force P=300lb/cos 35°=300/0.819 =366.23lb

b) Vertical component of force P=P sin35° =366.23x0.5736=210.06lb
