A beam with a length of 7 m and a mass of 110 kg is attached by a large bolt to a support at a distance of d = 3 m from one end. The beam makes an angle θ = 30 with the horizontal, as shown in the figure. A mass
M = 492 kg
is attached with a rope to one end of the beam, and a second rope is attached at a right angle to the other end of the beam. (Let up be the +y-direction and to the right be the +x direction.)

Find the tension, T, in the second rope.
Find the force exerted on the beam by the bolt. (Indicate the direction with the sign of your answer.)
Fbx =
Fby =
