A purple beam is hinged to a wall to hold up a blue sign. The beam has a mass of mb = 6.6 kg and the sign has a mass of ms = 16.8 kg. The length of the beam is L = 2.67 m. The sign is attached at the very end of the beam, but the horizontal wire holding up the beam is attached 2/3 of the way to the end of the beam. The angle the wire makes with the beam is ? = 32.4°
1.What is the tension in the wire?
2.What is the net force the hinge exerts on the beam?
3.The maximum tension the wire can have without breaking is T = 918 N.
What is the maximum mass sign that can be hung from the beam?
4.What else could be done in order to be able to hold a heavier sign?
A. while still keeping it horizontal, attach the wire to the end of the beam
B. keeping the wire attached at the same location on the beam, make the wire perpendicular to the beam
C. attach the sign on the beam closer to the wall
D. shorten the length of the wire attaching the box to the beam

A 1220-N uniform beam is hinged at a vertical wall at one end
and is supported by a cable that is attached to the beam at the
other end. A 200-kg load hangs at the end of the beam. The lower
end of the beam makes an angle of 30° above the horizontal, while
the supporting cable is attached to the wall at an angle of 40°, as
shown.
(a) Calculate the magnitude of the tension in the supporting
cable....

A plank of length l = 2m is hinged at one end to a wall. The
other end is being (temporarily) supported by a worker who is
holding it up with his hand, keeping the plank horizontal. The
plank has a mass of 20kg, and there is also a toolbox of mass 5kg
sitting on it, 50cm away from the worker (1.5 m away from the
wall). (a) Draw a free body diagram and an extended free-body
diagram for the...

A flaggpole of mass 5km and length 3.0 m is hinged at a wall and
supported by a horizontal position by a cable affected to the
flagpole at 2.0 M from the wait. The cable makes an angle of 25
with the horizontal. An iron plate of mass 1.5 kg is hanged at the
free end of the flagpole.
A. what is the tension in the cable.
B. What is the horizontal force excerted on the hinge of the
wall....
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down
A 4-m long, 150-kg steel beam is attached to a wall with one end connected to a hinge that allows the beam to rotate up and down. The other end of the beam is held in a horizontal position with a cable that makes a 27° angle with the beam and is attached to the wall (see (Figure 1) ). What is the tension force that keeps this beam in static equilibrium?

A cross was made between a plant that has blue flowers and
purple seeds to a plant with white flowers and green seeds. This is
a parental cross and the parents are homozygous for both characters
(color of the flower and color of the seeds). The resulting
offspring (the F1 generation) is allowed to self-fertilize.
Complete a Punnett square representing the F2 generation that
results from the above self-fertilization. The traits blue flowers
(B) and purple seeds (P) are dominant...

A beam that weighs 200 N is connected to a wall by a hinge so
that it makes an angle of θ = 30.0◦ with the horizontal. The beam
is 1.50 m long and is held in place by a cable that runs
horizontally from the end of the beam to the wall. A box that
weighs 100 N hangs from the end of the beam. Calculate a) the
tension in the cable connected to the wall and b) the...
