Poisson’s ratio in the book Mechanics of Materials and Integrated Learning System the calculated value for Structural Steel is 0.26 and our calculated value is 0.196629. This is a difference of 0.063371. This ratio only varies slightly so our values are accurate. In the book the elastic

Turing) published independently (as is often the coincidence in science) the basics of a new branch in Mathematics (and logic): computability or recursive functions (later to be developed into Automata Theory). <br> <br>The authors confined themselves to dealing with computations which involved

Toy cars have been played with by children for many years. Would one wonder the way a model or toy car rolls down a hill? One would think it would be because it has wheels‚ this is true but there is more to a car rolling downhill than it having wheels. Gravity is the force that is keeping all things on the ground. The heavier an object is the more gravity has an effect on its momentum. If you put a toy car on a downhill slope it will begin to roll because of gravity. The more the car weighs will

There are few things that I realized while reflecting on the life of Isaac Newton and his works. First‚ Isaac Newton became a key figure in the scientific revolution of the seventeenth century and is widely recognized as one of the most influential scientists of all time despite his humble beginnings. This fact made me understand that I can achieve something big in my life regardless of my roots. Newton said that his works were based on previous discoveries. It was an admission that his amazing

For this lab students used the following materials: silver pasco dynamics track‚ mechanics box- with pulley‚ black variable speed cart‚ Xplorer GLX (captures‚ analyzes‚ annotates‚ and stores data quickly and seamlessly‚ without being connected to a desktop computer)‚ 50g mass‚ string‚ meter stick‚ colored tape‚ and scissors.
