Homework Help: Shear stress with 4 bots

  1. Nov 11, 2011 #1
    1. The problem statement, all variables and given/known data

    A flange coupling is use to transmit torque of 1500 Nm between two shafts. The coupling has four 8mm dia. bolts equally spaced on a PCD of 175mm. Determine the shear stress on the bolts

    2. Relevant equations

    [itex]fs=\frac{F}{A}[/itex]

    3. The attempt at a solution

    Back of the book answer = 85.3MPa. but I don't know how they get this answer.

    It's ok, disaster averted.

    Just use t=F*r to convert the torque to a force acting on the bolt's.

    Unfortunately TAFE forgot to give me this formula before giving me this question.
