Had you ever considered the impact of culture on mental health? Have you witnessed an impact of culture on mental health treatment or willingness to seek help? Which approach do you think is more important – looking for mental disorders common across cultures, or looking for cultural syndromes? Do you think all treatments need to be empirically supported? Why do you think some cultures have higher rates of mental illness than other cultures?

Problem 4 (b) only Solve the question assuming that the pump pressurizing the cylinder is too weak to maintain pressure if a crack penetrates the wall. (9.5 MPa) (a) A cylindrical steel pressure vessel of 7.5 m diameter and 40 mm wall thickness is to operate at a working pressure of 5.1 MN m?². The design assumes that small thumb-nail shaped flaws in the inside wall will gradually extend through the wall by fatigue. If the fracture toughness of the steel is 200 MN m?³/² would you expect the vessel to fail in service by leaking (when the crack penetrates the thickness of the wall) or by fast fracture? Assume $K = \sigma \sqrt{\pi a}$, where $a$ is the length of the edge-crack and $\sigma$ is the hoop stress in the vessel. (b) During service the growth of a flaw by fatigue is given by $\frac{da}{dN} = A(\Delta K)^4$ where $A = 2.44 \times 10^{-14} (MNm^{-2})^{-4}m^{-1}$. Find the minimum pressure to which the vessel must be subjected in a proof test to guarantee against failure in service in less than 3000 loading cycles from zero to full load and back.
