An 18.4 kg beam is attached to a wall by a hinge and it hangs out horizontally.

1. An 18.4 kg beam is attached to a wall by a hinge and it hangs out horizontally. From the end of the beam, a 27.1 kg metal sculpture is hung. A cable is attached to the wall above the beam and is attached to the beam. The cable makes an angle of 18.9 degrees with the wall. It attaches to the beam 2/7 of the way down from the hinge. What is the tension in the cable?

2. A 31 kg, 7.71 ladder leans against a wall and makes an angel of 24.2 degrees with the floor. The ladder feels a coefficient of friction with the floor of 0.412. How far up the ladder can a 118 lb person go before the ladder slips down?

A 28.0 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?

A horizontal 14.9 kg beam 2.1 m long is attached to the wall by a hinge at its left end.

A horizontal 14.9 kg beam 2.1 m long is attached to the wall by a hinge at its left end. A cable is connected from the right end of the beam to the wall, at an angle of 27 ° above the beam, as shown below. A 55 kg sign is hung 1.6 m from the left end of the beam.Part A - Find the tension in the cable.Part B - Find the horizontal force exerted on the wall by the hinge.Part...

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?

In the figure shown, one end of a uniform beam that weighs 827. N is attached to a wall with a hinge.

In the figure shown, one end of a uniform beam that weighs 827. N is attached to a wall with a hinge. The other end is held up by a wire. So the beam is in static equilibrium. There is an unknown horizontal and an unknown vertical force on the hinge.(a) Find the tension in the wire.N(b) What is the horizontal component of the force of the hinge on the beam?N(c) What is the vertical component of the force of...

A 100 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 = 43°. The angle between the horizontal and the beam is 30 degrees.

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...

Consider a long (length = 15 m) uniform wooden beam (mass = 60 kg) attached horizontally to a wall that can only support a vertical load ( The horizontal component of the force of the wall on the beam is identically zero). There is a chandelier (mass = 40 kg) hanging at a distance = 4.21 meter from the end of the beam that is attached to the wall. There is a vertical cable hanging down from the ceiling that...

A 10kg weight is attached to a wall horizontally via a spring. The rest (equilibrium) length of the spring is 0.2m. The spring has stiffness coefficient k = 50. The weight drags along the ground, giving an effective damping coefficient of b = 40. We will ignore gravity and all other outside forces on the spring. If the weight is pulled to a position 0.5m away from the wall (thus +0.3m past equilibrium) and then flicked toward the wall at...

A 5 kg block is attached to a horizontally-mounted spring with a spring constant of 600 J/m2. The spring is extended by 10 cm from its normal length and the block is then released with an additional pull that imparts an initial velocity of 50 cm/s. The angular velocity (in rad/s) is A rad/s. The phase shift or off set (in degrees) is B degrees. The amplitude (in cm) is C cm. Please highlight where the given mass, spring constant,...
