A beam of length L=4m is subject to a distributed load which weighs
(that is acting downwards onto the beam) 80 kN/m. The load starts at
the right end of the beam and extends only to the half-way mark, x=L/2.
Determine the total weight of the load.
Determine the support forces R_{1} and R_{2}.
Determine the value of the internal shear force V(x) and
that of the internal moment M(x)
at x=0 (just to the right of R_{1} )
at x=1/4 L
at x=1/2 L
at x=3/4 L
at x=L (just to the left of R_{2})
