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.
Hookeâs Law. The extension of a spring or wire is directly proportional to the force applied provided the limit of proportionality is not exceeded. When a graph of force against extension is plotted for a material which obeys Hookeâs law it looks like the graph below. The gradient of this graph is the spring constant (k) which is measured in Nm-1.
