- A non-uniform beam has a length of 4.74 m and a mass of 63.7 kg. The beam is resting horizontally on two supports. The first support is located 1.31 m from the left edge of the beam and applies an upward force of 199 N to the beam. The second support is located 1.86 m to the right of the first support. How much upward force is applied on the beam by the second support?What is the FBD of the figure below:Can i get some help please
- A 8.08m long rigid beam with a mass of 145.4kg is supported at each end. A 66.0kg student stands 1.28m from support 1. How much upward force does each support exert on the beam?
