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.
Eating unprocessed beef, pork, or lamb was not linked to a higher risk for heart disease and diabetes. The study is the largest research review ever to attempt to tease out the health impact of eating processed vs. unprocessed red meat.The finding that all red meats are not equal when it comes to heart and metabolic disease risk has important implications for public health, says study researcher Renata Micha, PhD.ating one serving a day of processed meat -- or the equivalent of a single hot dog or two slices of salami -- was associated with a 42% increased risk for heart disease and a 19% increased risk for diabetes in the study, conducted by researchers from the Harvard School of Public Health.
