Problem # p010

Internal Shear Force and Moment

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.

1. Determine the total weight of the load.

2. Determine the support forces R₁ and R₂.

3. 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 R₁ )
   at x=1/4 L
   at x=1/2 L
   at x=3/4 L
   at x=L (just to the left of R₂)
