Answers - Essay ExampleHot rolling is a metal processing process that occurs above the materials recrystallization temperature. It uses full-size pieces of metals in the process, such as slabs. On the other hand, cold rolling entails metal processing below the materials recrystallization temperatures. It involves passing small pieces of metals with rollers.Hardwood has straighter and cleaner grain patterns. They possess higher density and are more fire resistant compared to soft timberland. Hardwood is more applicable for engineering works, making of floors and high-quality furniture. They also gull slower growth rates.Softwoods have a lower density and relatively cheap to in terms of cost. Softwoods have reduced fire resistance capacity. The woods also possess rugged grain patterns. Soft woods use is limited to low-quality furniture and is not preferred for engineering works (Bawa, 2009).By definition, OSB is a material of high mechanical properties, such that it becomes particul arly suitable for use in heavy load-bearing applications especially in construction works and industries. On the other hand, MDF is a wood product that is engineered by breaking down softwood or hardwood residuals to make wood fibers. The process often takes place in a defibrator, where it gets combined with resin and binder. The product has a higher density than plywood.Stress is pressure or tension exerted on a material object. short letter is a force that tends to pull or stretch an object to an extreme degree, usually, damaging levels. By definition, elastic modulus is the ratio of force exerted on an object to the ending deformation it undergoes. Plastic deformation is a process whereby force is exerted to a metal or plastic object to change its shape permanently. For the yield strength, it is a stress point where it is possible to produce a given particular plastic deformation amount. Toughness is the actual ability of any material to describe energy without fracturing
