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...
Question: A 4m, 500kg steel beam extends horizontally from
thepoint where it has been bolted to the framework of a new
buildingunder construction. a 70kg worker stand at the far end of
the beam.What is the magnitude of the torque about the point where
the beamis bolted into place.
Now this is what I have:
τ (grav)=-MgXcm where Mg is the net gravitational forceacting
on the object and Xcm is the moment arm between the rotationaxis
and center of mass....

A cable with negligible mass is attached to the end of the beam just above! the sign and extends to the wall, forming an angle of 30° with the beam. cable beam Physics is Phun Figure 2 WT 1173337 a)...
A 4.80-m-long, 550 kg steel beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 75.0 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the point where the beam is bolted into place?
Problem #2: 25 points A 24m long, horizontal beam is attached to a wall by a hinge. A support cable, 26 m long, is attached to the other end of the beam and attached to the wall 10m above the hinge, forming a 5, 12, 13 right triangle (HINT: leave sin and cos as a simple ratio of integers). The load hanging from the very end of the beam is 1000 Kg and the beam has a mass of 300Kg....
