Question

A 209.8 kg uniform, horizontal beam is hinged at one end and at the other is supported by a cable that is at 23 degrees to the vertical. The beam is 2.39 m long. Calculate the magnitude of the force (in N) at the hinge.

Answer #1

A 172.5 kg uniform, horizontal beam is hinged at one end and at
the other is supported by a cable that is at 24 degrees to the
vertical. The beam is 2.89 m long. Calculate the magnitude of the
force (in N) at the hinge.

A 171.4 kg uniform, horizontal beam is hinged at one end and at
the other is supported by a cable that is at 27 degrees to the left
of the vertical. The beam is 3.98 m long. Calculate the direction
of the force at the hinge (measured with respect to the
horizontal). Answer with a number in degrees.

A 110 kg uniform beam is attached to a vertical wall at one end
and is supported by a cable at the other end. Calculate the
magnitude of the vertical component of the force that the wall
exerts on the left end of the beam if the angle between the cable
and horizontal is θ = 39°.

In the figure, a uniform beam with a weight of 56.9 N and a
length of 3.75 m is hinged at its lower end, and a horizontal
force of magnitude 58.2 N acts at its upper end. The
beam is held vertical by a cable that makes angle θ =
20.8° with the ground and is attached to the beam at height
h = 2.04 m. What are (a) the tension in
the cable, (b) the x-component of the
force on...

A uniform steel beam (mass 43.7 kg, length 9.79 m) is hinged at
one end to a wall and has two wires attached at the other end. Wire
1 (length 4.67 m) is horizontal and is attached to the wall, and
wire 2 is vertical and is attached to the floor If the system is in
equilibrium and the tension in wire 2 is 130 N, find the magnitude
of the tension in wire 1, in
N.

A 23.0 kg beam is attached to a wall with a hinge while its
far end is supported by a cable such that the beam is
horizontal.
If the angle between the beam and the cable is θ = 57.0° what
is the vertical component of the force exerted by the hinge on the
beam?

Figure shows a safe (M = 430 kg) hanging by a rope (negligible
mass) from a boom (a = 1.9 m and b = 2.5 m) that consists of a
uniform hinged beam (m = 85 kg) and horizontal cable (negligible
mass). a) What is the tension in the cable? In other words, what is
the magnitude of the tension force on the beam from the cable? b)
Find the magnitude of the net force on the beam from the...

A 560-N uniform rectangular sign 4.00 m wide and 3.00 m high is
suspended from a horizontal, 6.00-m-long, uniform, 120-N rod as
indicated in the figure below. The left end of the rod is supported
by a hinge and the right end is supported by a thin cable making a
30.0° angle with the vertical. (Assume the cable is connected to
the very end of the 6.00-m-long rod, and that there are 2.00 m
separating the wall from the sign.)...

A
man with mass 80 kg begins walking out to the end of a 5 m long
beam that is supported by a hinge attached to a building at one end
and a cable that makes a 30° to the horizontal at the other end.
This cable can withstand 2000N of tension until it breaks.
a) How far can the man walk before the cable breaks?
b) Just when the cable snaps, what is the angular velocity?
Assume the only...

A 175 kg horizontal beam is supported at each end. A 310 kg
piano rests a third of the way from one end.
What is the vertical force on the support closest to the
piano?
N
What is the vertical force on the support furthest from the
piano?
N
