A 40 kg, 5.0 m-long beam is supported, but not attached to, the two posts in the figure.
A 37 kg , 5.0-m-long beam is
supported, but not attached to, the two posts in the figure. A 20
kg boy starts walking along the beam.
How close can he get to the right end of the beam without it
falling over?

A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...
A uniform, 8.0 m long, 1000 kg beam is resting on the floor and supported by a thin cable attached 2.0 m from the free end of the beam. The beam is supported at an angle of 30.0° above the horizontal. (a) Draw a free-body diagram of the beam.(b) Find the tension in the cable. (c) What are the x- and y-components of the force the beam exerts on the floor? 40.0° 2.0 m 30.00 Upload the work (in word,...
A 2.000 m long horizontal uniform beam of mass 20.00 kg is supported by a wire as shown in the figure. The wire makes an angle of 20.00 degrees with the beam. Attached to the beam 1.400 m from the wall is a ball with a mass of 40.00 kg. What are the vertical and horizontal components of the force of the wall on the beam at the hinge?
A uniform aluminum beam 9.0 m long, weighting 300 N rests symmetrically on two supports 5 m apart. A boy weighting 600 N is standing initially at position x = 4 m to the right from support A a. Find the normal forces exerted by both supports on the beam b. Imagine now that the boy starts walking to the right along the beam. How far beyond the point B can the boy walk before the beam tips?
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 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. A mass of 75 kg is hung from the beam 3 meters away from the hinge (see (Figure 2)). Now what is the tension force...
