For a brittle material that has a crack of length 0.04mm, and flexural strength and elastic modulus values of 88.1 MPa and 61 GPa, respectively. The critical stress (in MPa) required for crack propagation is 17.9MPa, calculate the specific surface energy of this brittle materials.
Assume you are given a spherical joint where the ball has a radius of 20 mm and socket has a radius of 22 mm. If the contact load is 50 N, E = 210 GPa, and ν = 0.3, determine (a) the radius of the contact area, (b) the maximum contact pressure.
