Balance force equations

  1. Sep 29, 2016 #1
    1. The problem statement, all variables and given/known data
    IMG_20160929_152147.jpg
    Given:
    a=10m
    l=18m
    P=18kN
    angle alpha = 35 deg

    The task is to calculate the base reaction forces on A and on B

    2. Relevant equations


    3. The attempt at a solution

    This is my attempt on creating the balance equation system.

    When replacing the variables with numbers, and trying to solve the equations, I get , in my opinion , unrealistic answers.

    Is there any mistake this far?

    IMG_20160929_154916.jpg So this is correct as well?

    I guess I found my mistake.
