a. A uniform steel girder AB is 6.0 m long and has a mass equivalent to 4.0 kN acting at its centre. The girder rests on two supports at C and B as shown in figure 2. A point load of 20.0 kN is attached to the beam as shown. Prove that the value of the force F would cause the beam to just lift off the support B.
