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 constant, E, is the modulus of elasticity, Young's modulus or the tensile modulus and is the material's stiffness. Young's modulus is in terms of 10 6 psi or 10 3 kg/mm 2. If a material obeys Hooke's Law it is elastic. The modulus is insensitive to a material's temper.he ultimate strength refers to the point on the engineering stressâstrain curve corresponding to the stress that produces fracture. The following are basic definitions and equations used to calculate the strength of materials.
