Assemble a pair of parts A and B with serrated teeth as shown in the figure on the right.A compressive load of 24 kN is acting on the combined structure.The compressive load is transmitted by the three meshing teethTo. Shear stress and compressive stress (contact) generated in the tooth at this timeFind each tactile stress.
Determine the resulting maximum value of the normal stress. Specify the orientation of the plane on which these maximum values occur. **The answer is tensile stress is 0 ksi at 90 degrees. **The answer is compressive stress is 7 ksi at 0 degrees. Can you explain how that is? This was my thought process: I know that tensile would be zero because the force P is actually going inwards and not outwards. I know that means that there would be a compressive force. I am confused on the angles, how is a tensile force going 90 degress if there technically is no force in the tensile direction. And how is there a compressive force at 90 degrees if there is a stress? thank you!
