Temperature & Times for Cooking Chicken. When cooking chicken, make sure to cook thoroughly, so there is no pink and the flesh is opaque all the way through. If you are using a meat thermometer, you can use it to determine when the meat is done; chicken should be cooked to 165 degrees.
Hooke's law. When studying springs and elasticity, the 17áµÊ° century physicist Robert Hooke noticed that the stress vs strain curve for many materials has a linear region. Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring.
The limit of proportionality is the is the point beyond which Hookeâs law is no longer true when stretching a material. The elastic limit is the point beyond which the material you are stretching becomes permanently stretched so that the material does not return to its original length when the force is removed.
