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.
1 The deforming force may be applied to a solid by stretching, compressing, squeezing, bending, or twisting. Thus, a metal wire exhibits elastic behaviour according to Hookeâs law because the small increase in its length when stretched by an applied force doubles each time the force is doubled. Mathematically, Hookeâs law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.
