Static-equilibrium problem 10

Добавлено в закладки: 0

A 26.4 kg beam is attached to a wall with a hinge and its far end is supported by a cable such that the angle between the beam and the cable is 90°. If the beam is inclined at an angle of θ=31.7° with respect to horizontal, what is the magnitude of the horizontal component of the force exerted by the hinge on the beam?

Solution of the example in word.
