A beam is attached to a vertical wall with a hinge. The mass of the beam is 1800 kg and it is 4 m long. A steel support wire is tied from the end of the beam to the wall, making an angle of 30° with the beam (see the figure below).

1)Calculate the tension in the support wire. Assume the beam has a uniform density.

kN

2)What is the vertical component of the force exerted by the hinge on the beam?

kN

3)What is the horizontal component of the force exerted by the hinge on the beam?

kN
