A 4.0-m-long 500 kg steel beam extends horizontally from the point where it has been attached to a building that is under construction. A 65 kg construction worker is standing at the far end of the beam. A. Sketch the situation, label variables and centers of gravity. Collect known quantities. B. Where is the center of gravity of the beam? C. What is the gravitational torque on the connection point if no one is standing on the beam? D. What...

A raccoon has climbed a building downtown where the
raccoon finds a beam that has been installed to hold a sign for a
business. The uniform beam, which is 3.2 meters long and has a
weight of 225 N, is attached to the wall of the building by a hinge
and is supported by a light wire that makes an angle of 30.0° above
the horizontal. The raccoon, who has a mass of 25 kg, walks onto
the beam, not...

The beam ABC has a mass of 78.0 kg and is supported by the rope
BDC that runs through the frictionless pulley at D. The winch at CC
has a mass of 44.5 kg. The tension in the rope acts on the beam at
points B and C and counteracts the moments due to the beam's weight
(acting vertically at the midpoint of its length) and the weight of
the winch (acting vertically at point C) such that the resultant...

Cross section at the wall Problem Statement: Consider a round beam of diameter d= 25 mm, length L = 10 mm, cantilevered (clamped) to the wall (as shown in the figure), loaded by P=5.5 kN. Further pay attention to points A, B, and C (half way between A and B) in the cross section at the wall, where the bending moment is maximum. Hint: The location of the centroid of half a circle can be found in Table A-18. Hint:...
