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.
athematically, Hooke's law states that F=-kx, where x is the displacement of the spring's end from its equilibrium position (a distance, in SI units: meters); F is the restoring force exerted by the spring on that end (in SI units: N or kgÂ·m/s2); and k is a constant called the rate or spring constant (in SI units: N/m or kg/s2).
