I really appreciate help to solve this problem. I need to find all the $4$ reactions and the equaions of defletion. Please solve by doing the cuts in the beam. I know that the answers should be: reactions in the first and last pin should be $-6\mathrm{.}857$ N and in the second and third pin the reactions should be $+18\mathrm{.}857$ N$.$ Please show me step by step. The distributed load is of $3$N$/$m it is going downwards and goes from $2$m to $10$m$.$ The $1$st pin is at $0$m $,$ the $2$nd pin is at $2$m $,$ the third pin is at $10$m and the last pin is at $12$ m$.$ The E is $200$GPa and the inertia is of the rectangular cross section of b$=0\mathrm{.}5$ m and h$=1$m
