Determine magnitude of force P and its horizontal component | Vector Mechanics | Engineers Academy

Vector mechanics for engineers by Beer and Johnston solution


2.28 Member BD exerts on member ABC a force P directed along line BD. Knowing that P must have a 240-lb vertical component, determine (a) the magnitude of the force P, (b) its horizontal component.

2.29 The guy wire BD exerts on the telephone pole AC a force P
directed along BD. Knowing that P must have a 720-N component
perpendicular to the pole AC, determine (a) the magnitude of the
force P, (b) its component along line AC.
