QUESTION:
(II) A uniform steel beam has a mass of 940 kg. On it is resting half of an identical beam, as shown in Fig. 9–44. What is the vertical support force at each end?
ANSWER:
Step 1 of 4
We need to find out the vertical support force at each end of a uniform steel beam which is resting half of an identical beam. The CG of each beam is at its center. Calculate torques about the left end of the beam, and take counterclockwise torques to be positive. The conditions of equilibrium for the beam are used to find the forces that the support exerts on the beam.
