laminated materials fibre composites particle composites. A laminate contains thin pieces of material fused together. Common examples are plywood and car windscreens. Wood is durable when exposed to a ductile force equivalent to its grain‚ but if the strength is across the particle it splits simply. A windscreen is made in a parallel way; two sheets of reinforced glass are bonded to a piece of clear plastic in a sandwich. If the glass smashes‚ the plastic grasps the wrecked pieces together. Wood and bone

was tested three times using an Instron load frame and the BlueHill data acquisition software. The data from each test was used to determine valuable material properties such as ultimate tensile strength‚ modulus of elasticity‚ and yield strength. Other calculated properties included true fracture strength‚ percent reduction of area‚ and percent elongation. These material properties were used for comparing the materials to each other‚ and to define the material as brittle or ductile. The true stress

The Truth About A Quick First Step What is a First Step The first step is basically the first step you take of the dribble‚ when driving towards the basket‚ in order to beat your opponent to the hoop. It does take the right strength‚ coordination‚ and the right boost of energy‚ which is required from the leg you typically use to make your first step‚ but to become a better player‚ you should condition both legs to be able to take the first step when driving to the hoop. You will find that with the
