a) A cantilever beam in Figure 2.1 is subjected to a distributed load w(x) = kx² as shown in the figure. Take L =10 m andk = 2N (m3. Make

a cut at distance x from x=0 (the left end of the beam),and derive expressions for the internal resultant loadings at the cross-section as functions of x Normal force, N(x) Shear force, V(x) Bending moment, M(x)
