31. Engineers are concerned that the bridge might not be able to handle normal stresses if the abutments continue to move. 32. Low-impact exercise, elimination of drug and alcohol use, and regular meditation can help to restore normal stress responses in hypokinesia patients. 33. Coulomb's friction hypothesis is used to determine the combination of shear and normal stress that will cause a fracture of the material. 34. Another variant of normal stress is the "'hoop stress "'that occurs on the walls of a cylindrical vessel filled with pressurized fluid. 35. The normal stress , or fluctuating pressure acts as a forcing term ( much like pushing a swing introduces a forcing term ). 36. A normal stress response to having witnessed the attacks or having watched them on television is likely to subside far more quickly. 37. Yet insurance companies increasingly don't accept the normal stresses of labor on the body as a reason to stay in the hospital. 38. This allows for a simple static equilibrium calculation, considering only soil weight, along with shear and normal stresses along the failure plane. 39. The principal normal stresses can then be used to calculate the von Mises stress and ultimately the safety factor and margin of safety. 40. Antenatal depression was once thought to simply be the normal stress associated with any pregnancy, and was waved off as a common ailment.
