Definitions of stress and strain. Nominal stress: the force on the object divided by the original area. True stress: the force on the object divided by the actual area. E.g., when necking occurs the true stress is the force applied divided by the area of the neck. The unit for stress is Nm-2, or Pa. Nominal strain: change in dimension / original dimension. This is also known as the engineering strain, and is strictly only true for very small displacements.
Fresh meat that wasnât mentioned directly by the agency is non-processed poultry and fish. Meats like fresh chicken and turkey have long been recommended as good sources of protein, and options to replace red or processed meat in the diet. The silver lining for Americans is that even though your Christmas ham is on the no-no list, at least the star of the Thanksgiving gets a pass.
Most processed meat contains pork or beef, but also can include other red meats, poultry, and organs or blood. The WHO report looked at more than 800 studies on cancer and consumption of red meat or processed meat across many different countries, ethnicities, and diets.
