$1.$ Solve for the reaction Ve

$2.$ Solve for the reaction of internal construction hinge at d$.$

$3.$ Consider the whole system. Summation of forces vertical $=0$

$4.$ Summation of forces horizontal $=0$

$5.$ Consider this: There is an internal construction at point d$,$ and therefore the beam does not support any moment at that point. At point c$,$ the connection is rigid and is moment resistant. Taking into consideration the span cd$.$

$6.$ Moment of the overhang load which is at the left of support c$.$

$7.\backslash$Sigma Mc $($left and right moment$).$

$8.$ Moment at the ground support at a$.$

$9.$ Shear value at the left of support c$.$

$10.$ Shear value at the right of support c$.$

$11.$ For the maximum positive moment at span de$,$ Consider the triangular load at the top. Reaction for d and e imposed by the triangular load.

$12.$ Solve for the distance x for the triangular load.

$13.$ Shear and moment equation at distance x$.$

$14.$ Solve for maximum moment.

$15.$ Solve for the approximate equivalent x from point d for the triangular and rectangular load.
