Shear stress in bending member question

  1. May 6, 2015 #1
    Hi all,

    I was just wondering if someone could confirm that my answer to the below question is correct. The point where the question asks you to find the shear stress is at 2m (n). However, I don't believe this value needs to be included in the calculation anywhere?

    1.) You are incredibly careless with units in this calculation. What are the units of stress? (Hint: it's not kN.)

    2.) Your calculation of the shear stress at B contains a mistake in calculating the value of Q.

    Oh! My bad!!! Been a long day.

    I will adjust to MPa or N/mm^2
