Question

We have a restaurant sign that weighs 150N and we will hang it using a beam and a cable as shown in the figure. The mass of the beam is uniform and its weight is 50N. We do not know the length of the beam (express it as L). The cable has no mass, and makes an angle of 30 ° with the beam. The magnitude of the gravitational force of the gonze that supports the beam is approximately:

Using the same situation as the previous probl of the restaurant sign weighing 150N and the beam weighing 50N. What will be the direction of the strength of the gonze that supports the given beam as the angle it makes with the horizontal or with the beam?
