In the cantilever of Figure (b), the left hand end is free and the right hand end is firmly fixed; the right hand end is called the constrained end.
Bending moment (BM)
At x in Figure 6.22 , M = −5 kN × x
i.e. M = −5x .......(6.21)
(a straight line)
Shearing force ( SF)
At x in Figure 6.22, F= −5 kN (a constant)........(6.22)
For equations (6.21) and (6.22), it can be seen that the bending moment and shearing force diagrams are as shown in Figure(c).
