A uniform steel beam of mass m1= 300.0 kg is held up by a steel cable that is connected to the beam a distance L= 5.0 m from the wall, at an angle θ= 40.0∘ as shown in the sketch. The beam is bolted to the wall with an unknown force F⃗ exerted by the wall on the beam. An object of mass m2= 50.0 kg resting on top of the beam, is placed a distance d= 4.0 m from the wall. For simplicity, assume the steel cable to be massless. Use g=9.8 m⋅s−2 for the gravitational acceleration.

Question

A uniform steel beam of mass m1= 300.0 kg is held up by a steel cable that is connected to the beam a distance L= 5.0 m from the wall, at an angle θ= 40.0∘ as shown in the sketch. The beam is bolted to the wall with an unknown force F⃗  exerted by the wall on the beam. An object of mass m2= 50.0 kg resting on top of the beam, is placed a distance d= 4.0 m from the wall. For simplicity, assume the steel cable to be massless. Use g=9.8 m⋅s−2 for the gravitational acceleration.

(a) Find the tension (in Newton) in the cable. Start by drawing a free-body diagram for the beam, then find equations for static equilibrium for the beam (this will involve force equations and torque relations).

(b) Find the horizontal and vertical components of the force (in Newton) that the wall exerts on the beam.
