Homework Help: How to calculate the force required in this case?

  1. Oct 26, 2013 #1
    1. The problem statement, all variables and given/known data
    I have two PCB (printed circuit board), and they are glued by adhesives, as show in the pictures.
    And the location of the adhesives are indicated on the picture (please notice that NO adhesive is applied between the PCB boards).

    50N force is applied on the upper PCB for each case (X, Y and Z directions). The objective of the use of the adhesive is to prevent the PCB from moving. And i need to calculate how much force per mm2 acting on the adhesive.

    Suppose the adhesive applied is 1mm thick. How to calculate the average force acting on the adhesive in terms of N/mm2 in each case?

    i have tried to find the answer, but i don't think my answers are correct. Because the forces acting the adhesive don't look like pure tensile or shear forces.

    Can someone please help?
