The shear force diagram for a cantilever beam of span L as shown in figure, subjected to a concentrated load W at the free end and a uniformly distributed load of intensity w /m length is :
1
Rectangular with parallel sides of (W + w. L) at the two ends.
2
Trapezium with parallel sides of W at the free end and (W + 0.5 w. L2) at the fixed end
3
Right angled Triangle with zero value at the free end and (W + w. L) at the fixed end.
4
Trapezium with parallel sides of W at the free end and (W + w. L) at the fixed end
