Experimental Determination of Young’s Modulus of Elasticity of Timber and Metals

Elasticity is a property of material, which is manifested as reversible deformation under applied load. This reversible or elastic deformation is through stretching of inter-atomic bonds and therefore, there is an associated volume change with this type of deformation. Every material resists its deformation by the load applied onto it. In elastic deformation regime this resistance is measured by modulus of elasticity. Thus modulus of elasticity is a measure of resistance of a material against reversible or elastic deformation. Depending upon mode of loading – tensile, shear etc. there are different modulus of elasticity like Young’s modulus of elasticity (in tensile loading), Shear Modulus of elasticity (in shear loading) etc. Young’s modulus of elasticity is a very important property of…

Flame test lab report

Intro: The flame test is a procedure used by chemists to identify the presence of specified metal ions, based on the color the flame that appears along with it when it’s heated. Our flame test was in lab class, where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced, the second one was to identify unknown metals based on their flame color . Based on our chemistry classes there are two ways of getting the atoms excited: a) Through heating ; example by using flame as in the flame test so the atom electrons can be induced to…

What is an alloy?

An alloy is a solid solution or homogeneous mixture of two or more elements where a material with better or different properties is produced. The range of alloys produced depends on the solubility of the constituents and the proportion of them. The number of possible alloy combinations is almost endless since any metal can be alloyed in pairs or in multiples. Alloys can be classified into two main categories:Interstitial alloy. It is when smaller elements, such as boron, carbon, nitrogen, or silicon, fill the spaces or interstice of the main metallic structure or solvent. For example, steel is an interstitial alloy in which carbon atoms fill the holes between the crystal structures of iron. Substitutional alloyIt is formed when the…

Niobium’s use in Nuclear Reactors

Niobium, with a chemical symbol of Nb, is the lustrous light gray ductile metallic element that resembles tantalum chemically, and proves to be an extremely essential yet fascinating transition element. With an atomic number of 41, niobium combines strength, a high melting point, resistance to chemical attack, and a low neutron absorption cross-section. All of this promotes its use in the nuclear industry, especially in control rods of nuclear reactors. The prices of niobium are reasonable too, at a mere $75/lb, and are maintained by the largest producer to avoid market perception of a monopoly situation (Winter). Thus, niobium acts as a key element in nuclear fission reactors, due to its enormous strength, high melting point, resistance to corrosive chemicals,…
