Question

The 3.0-m-long, 90 kg rigid beam in the following figure is supported at each end. An 82 kg student stands 2.0 m from support 1. (Figure 1) Part A How much upward force does the support 1 exert on the beam? Express your answer to two significant figures and include the appropriate units. F1 = 980 N Part B How much upward force does the support 2 exert on the beam? Express your answer to two significant figures and include the appropriate units. F2 = 710 N Figure 1 of 1 2.0 m 3.0 m Support 1 Support 2

Step 1

Given: Mass of the beam (m1) = 90 kg Mass of the student (m2) = 82 kg Distance of the student from support 1 (d) = 2.0 m Total weight = Weight of beam + Weight of student Total weight = m1*g + m2*g Total weight = 90 kg * 9.8 m/s^2 + 82 kg * 9.8 m/s^2 Total weight Show more…
