Aluminium

particles have high penetration ability and low ionisation ability, beta particles can travel over one centimetre into a human body, they can travel through paper and sometimes aluminium, however if the aluminium is thick it should be able to stop the beta particles by absorbing them, or cause them to bounce of the surface of the aluminium. Beta particles are very light, they are 700 times smaller than an alpha particle and can travel 0.50m. Gamma radiation has very high penetration ability and…

Qn1 Ans Decision tree analysis will involve step determination of the chemical and physical characteristics of this chemical. By knowing them, it will be very easy to determine the best control method to be employed. Firstly, the compound is corrosive and it therefore suggests that it is highly reactive and use of water and any other chemicals that can lead to an undesired chemical reaction will be ruled out. Also, the spilled chemical is producing fumes, mostly it suggests that it is either a…

in the centre, which were wrapped in bubble wrap and taped. A polystyrene lid was also cut out and placed on top of the inner polystyrene cup. Each layer of polystyrene and paper cups were wrapped in aluminium foil. We also, covered the outside and bottom of the thermos with polystyrene and aluminium foil. Finally, we covered the hole in which the heat probe was inserted with sticky tape. Throughout the construction of the thermos, we tried to imitate the mechanisms used in a commercial thermos…

space such as motor generators and transformers. Figure 2: Magnet wire 3.0 Material Analysis on Magnet Wire 3.1 Wire Interior Material Properties: Commonly, the magnet wire uses copper as the main material, while occasionally aluminium. Physically, copper has a yellowish red appearance and when polished develops a bright metallic lustre. Copper possesses a face-centred-cubic (FCC) crystal structure, with Atomic Packing Factor (APF) of 0.74. Copper is tough, ductile, and…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

Aluminium Aluminium is one of the most widely used metals in the world today. This is all down to its various properties, these include low density which means low weight. It is also very malleable, easily machined, provides excellent resistance to corrosion and has good electrical conductivity. Another advantage of aluminium is that it is widely recyclable. Lightweight: With a specific weight of 2.7g/cm³, aluminium is used in many forms of transport including…

Chosen topic: Vaccination Question: Should the HPV vaccine be compulsory for girls ages 11-20. What is HPV? The human papillomavirus or HPV is the most common sexually transmitted infection in the world and the leading cause of cervical cancer. The virus is spread via skin to skin contact and so is developed by 4 out of 5 people in NZ . There are over 100 types of HPV of which they are split into high risk and low risk. High risk types are those that are associated with the development of…

3. Results and discussion 3.1. Microstructural and EDX analysis Fig. 1 and 2 show the surface morphology and EDX spectrum of FC and alum, respectively after coagulation/flocculation. The EDX analysis shows the adsorption of CB on FC and alum. As determined by EDX, detailed chemical composition of the dried flocs of FC and alum are presented in Table 1 and show that major elements of FC flocs are N, Fe, O, Cl, and of alum are N, Al, O, K, O, S. The weight % of element N defined the…

Will, Praise and Blame” included in Free Will, J.J.C Smart presents the thesis that metaphysical freedom is self-contradictory. As part of this claim, Smart forwards the analogies of the aluminium and the china plates (Smart 67). Having the knowledge of physical properties, the likelihood of a plate made of aluminium breaking when dropped is “not an open possibility” (Smart 66). Correspondingly, having knowledge of the china plates properties; there are factors of chance such as, the height…

CHAPTER 1 INTRODUCTION 1.1 Introduction Towing is a process of transporting or relocating the vehicle desired from one place to another. The process of towing may become essential whenever engine failure occurs of the vehicle or the trailers that are meant for transport are to be shifted from a place to another. So it is important to design a proper towing hook that is capable of withstanding various loading condition without any failure for long life. Also tow hooks are used to transport…
