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.
For elastic springs, the relationship between the applied force and the distance the spring moves is called Hooke's Law. F = -kx (1). The negative sign is used because F is the restoring force of the spring, which is in the opposite direction from the applied force of the hanging mass. The restoring force is therefore in the opposite direction from the displacement of the spring.
