A (3.0-mathrm{m})-long rigid beam with a mass of (100 mathrm{~kg}) is supported at each end, as shown

Question:

A \(3.0-\mathrm{m}\)-long rigid beam with a mass of \(100 \mathrm{~kg}\) is supported at each end, as shown in Figure P8.43. An \(80 \mathrm{~kg}\) student stands \(2.0 \mathrm{~m}\) from support 1 . How much upward force does each support exert on the beam? image text in transcribed
