    1. The problem statement, all variables and given/known data
    To find the reaction at A and B. (See image below)

    2. Relevant equations
    Moments and Area


    3. The attempt at a solution
    Area of load: (0.3)(6) = 1.8kN
    Moments about A: -(6)(0.15) + RB(0.6) = 0 --> RB = 1.5kN


    4. The error and question
    I get the reaction force at B to be 1.5kN but the answer states that it is 0.45kN. What am I doing wrong?

    "-(6)(0.15) " is wrong.

    Oh yes. It's -(1.8)(0.5). Found 1.8 in the step earlier and forgot to put that in. Thanks.
