The shear force at the ends of a simply supported beam carrying a uniformly distributed load of w per unit length is
A
Zero at its both ends
B
$${\text{w}}l$$ at one end and $$ - {\text{w}}l$$ at the other end
C
$$\frac{{{\text{w}}l}}{2}$$ at one end and $$ - \frac{{{\text{w}}l}}{2}$$ at the other end
D
$$\frac{{{\text{w}}{l^2}}}{2}$$ at one end and $$ - \frac{{{\text{w}}{l^2}}}{2}$$ at the other end
Correct Answer: $$\frac{{{\text{w}}l}}{2}$$ at one end and $$ - \frac{{{\text{w}}l}}{2}$$ at the other end
