15. Rotational Equilibrium

Beam / Shelf Against a Wall

Physics, Torque (11 of 13) Static Equilibrium, Hanging Sign No. 5

A beam 200 kg in mass and 4 m in length is held against a vertical wall by a hinge on the wall and a light horizontal cable, as shown. The beam makes 53° with the wall. At the end of the beam, a second light cable holds a 100 kg object. Calculate the angle that the Net Force of the hinge makes with the horizontal (use +/– for above/below +x axis, and use g=10 m/s2.)<img src="https://static.studychannel.pearsonprd.tech/courses/physics/thumbnails/images/09218bae"alt=""/>

Beam supporting an object

A beam 200 kg in mass and 6 m in length is held horizontally against a wall by a hinge on the wall and a light rod underneath it, as shown. The rod makes an angle of 30° with the wall and connects with the beam 1 m from its right edge. Calculate the angle that the Net Force of the hinge makes with the horizontal (use +/– for above/below +x axis, and use g=10 m/s2.)<img src="https://static.studychannel.pearsonprd.tech/courses/physics/thumbnails/images/412ef8c5"alt=""/>

The figure shows a 75 kg construction worker sitting on a massless beam with a length of 3.0 m. If the tension in the cable is 1100 N, how far from the left end of the beam is the construction worker sitting? <img src="https://media.pearsoncmg.com/aw/aw_knight_cp_4_du/msa/content/practice-test/img/CH08_Question01.jpg" alt="A construction worker sits on a 6.0 meter long horizontal beam, 2.0 meters from its right end. A cable extends upward and leftward at a 30 degrees angle above the horizontal from the right end of the beam to the wall." />
