Question

The next two questions refer to this situation: A uniform steel beam resting on two supports has a length L = 6.00 m and a mass M = 78 kg. The right support is l = 4.0 m from the left end of the beam. 24. When a student of mass m = 60 kg is located a distance x = 2.2 m from the left end, what is the magnitude of the force exerted by the right support on the beam? A) 676 N B) 897 N C) 988 N D) 1046 N E) 1352 N 25. What is the maximum value of x that the student can reach before the beam tips over? A) 4.3 m B) 4.8 m C) 5.1 m D) 5.3 m E) 6.0 m (beam will never tip over)

Step 1

Since the beam is uniform, its center of mass is at the middle, which is at L/2 = 6.00 m / 2 = 3.00 m from the left end. Now, let's consider the torques acting on the beam. We can choose the left support as the pivot point, so the torque due to the weight of the Show more…
