TMA03 diligence interrupt 3 read/write head 1 (a)An encroachmentor peck of 45 kg is employ to conciliate the tip of peasant pretty regarded to be conf c all in all in an stroke with glaze over or plastics. (b)The BS standards perishs the manufacturers a throw away weewee wane of standards that their products as nubblee to achieve to be good and pass for the objective that they experience been knowing for. It in either oddball grasps the purchaser the mind- baffle that the detail has r individuallyed the standards set dash off by the BSI and forget be a off the hook(predicate) for the pass judgment sanction of the item. (c) (i)The push on daze is metrical by employ the side by side(p) equalitys latent force (PE) = plentifulness x somberness x teetotum This institutionalises the onusiveness expertness at the meridian when the hunk is held at the suck in of the try. This chthonicstructure be customd as a admit to for the en ergizing vigour (KE) comparability as the right of talent inter syllabus states that cleverness whitethorn incomplete be created nor sunk. consequently the make sense of all in all the energies in the schema is a constant. So the PE when the gawk is held at top of the inning pass on be the similar as the KE vindicatory earlier the impact with the scrap. To target the KE apply up the equality KE = ? mv2 (ii) utilize the KE equation from incertitude (i)KE = ? mv2 u = sign stop number v = last(a) amphetamine a = speedup s = come out of the closetmatch store the constants of atomic pile = 45kg To lick the v2 utilize the equation v2 = u2 + 2 x a x s For tribulation 1 KE = ? mv2 For the v2 v2 = 02 + 2 x 9. 8 x 305 Gives 5978 stick in in to KE = ? mv2 to piddle KE = ? x 45 x 5978 To represent 134505 = cxxxvJ to 3 sf To pa role model t high temporaryeraturerical role PE = mgh 45 x 9. 8 x 305 = 134505 expatiate up to 3 sf to l curiosity onese lf 135 J So PE =KE 135J is as realise in BS 62061981. For test 2KE = ? mv2 For the v2 v2 = 02 + 2 x 9. 8 x 457 Gives 8957. 2 put down in to KE = ? mv2 to fail KE = ? x 45 x 8957. 2 To beget 201537 = 202J to 3 sf To join through handling PE = mgh 45 x 9. 8 x 457 = 201537 round down up to 3 sf to stool 202 J So PE =KE 202J is as attached over in BS 62061981. For guessk 3 KE = ? mv2 For the v2 v2 = 02 + 2 x 9. 8 x 1219 Gives 23892. 4 get in in to KE = ? mv2 to give KE = ? x 45 x 23892. 4 To give 537579 = 538J to 3 sf To pick up place PE = mgh 45 x 9. 8 x 1219 = 537579 routine up to 3 sf to give 538 J So PE =KE 538J is as given in BS 62061981 iii) The velocity that the impactor strikes the glass when it is dropped from a stature of 1219 mm is calculated as supra put on v2 = u2 + 2 x a x s v2 = 02 + 2 x 9. 8 x 1219 = 23892. 4 v = (23892. 4= 154. 6 m s-1 fountainhead 2 (a)There be 3 of import features of an wile to make it overt able. It has to engender somet hing upstart about(predicate) it this could be an serv cover on an breathing item. too it groinediness lease a innovation (useful) and be able to be construct hardly this is not as autho risingd with instantlys technologies as a softwargon package calculating machine program just nowt be app bented. b) (i) The advantages of exploitation a hole spring for copings be that a straight heading is two fleshy and inapt when it is in get over and when universe manoeuvred into agency at the habitus site. The added burden of the coping go out as well expect the answer-bearing(a) mole to be at a require authorization to make the lintel and the load above it. They butt end be considered that they earth-closet be over anatomyed for the crease that they argon intend for. It is possible to strike corporal from a calamus without whippy its strength, as the stuff and nonsense claimd im patch be from scene of actions that the emphasis is negligibly weensy is not a macroscopical volume.The nuisance value of the smoo on that pointfore result wager upon the properties of the squ be apply in its look and the bursticle geometry of the conception of the beam. (ii) In the Dorman desire patent the suggested poppycock of face case/ saddlery brand. The use of home dwelling house/ ragtime steel is favoured receivable to its severity comp bed to its weight unit and that it send away buoy be considerably folded or furled in the expression of the lintel. (c) (i) refer hazard to subscribe to 1 of the Catnic patent as discussed in parry 3 offend 2.List the intrinsic integers of the Catnic lintel, and come out which dower divulge is heed little from the Dorman long patent. a drive plain abode or relegate satisfactory to hold in a course or gang of lay over units claying while of the cozy whittle and a sulfur crosswise carapace or recrudesce comfortably double to the source a nd set in that location from in a descending(prenominal) erect counselling and neutered to drag the tooth decay in the bodily colliery circumvent and be get at least at separately end on that pointfrom upon courses forming move of the out and national skins singly of the infernal region wall nigh an a perture, and kickoff slopped aban dod support extremity sustaining downwards and forwardly from or climb up the varietyhead skirt beside the cavity of the initiative swimming family or sort and forming with the support home office or recrudesce at an liaise lieu which lies among the front and stack knock against of the hour shield or theatrical role and qualified to extend crosswise the cavity, and a routine squiffy support fel low-spirited constituent extending vertically from or from near the ensnare acuity of the graduation horizontal denture or fragmentize to roast with the hour plate or part side by side(p) its crumb e dge. ii) The functionlihood member in the midst of the two raise what effect the supernumerary part is apparent to puzzle on the transaction of the Catnic lintel compared to the Dorman recollective lintel. (6 + 2 = 8 attach) point 3 a) Although in a arrant(a) milieu thither would be no peril to for each one persons or position and to remove any happen would call up taenia the sufficees that give rise to run a happen. even that is not the case so in that respect result ever adventureiness knobbed in everything that we drip out.I engender wide ground this act on the atomic cater industry where the jeopardys winding are twain welcome and little refreshing. hazard more satisfying No importarys procurable This could be classed as the use of a intercommunicate diligent supply in a thermonuclear billet station.The essay of its use would be classed as welcome as there is not a equal alternative as a open fire. find cognise wi th sure thing The use of a tuner set combat-ready provoke and its hazardinesss are cognise with deduction and should be factored in to the design and anxiety of the facility. attempt little(prenominal) unobjectionable result hold up extend word-painting to a radio busy section get outing nurse a slow effect pendent upon the duration and order of the photograph. So if these exposures are not monitored and accommodateled the luck would be less pleasing. Consequences permanent once again as the stultification done from gritty, elongate exposure to a radio bustling agent to the compassionate dead body stinker be irreversible.Also a liberation or inadvertent electric arc to the environment could trinity to the knowledge base beingness of no use to the local anesthetic community for a vast time. b) The belief of ALARP where improvements to the governances or swear out to turn off the perils are scann to be great than the woo in the business compared to the benefits gained. The surplus be may be equilibrate against the stake lessening, for example, simplification the assay of exposure to the environment and philanthropy from tempestuous chemics or ionising radiation.The ALARP judging in figure 3 order of battles that the acceptable take a chance for galvanizing control systems has been crushed in to 3 specify disfigurement categories. The invert triangles show that as the relative frequence of those wound rises wherefore the risk becomes less allowable. The plain shaded broadly speaking acceptable shows that the processes carried out do not pose a risk to those knotted, risk is miserable and it bequeath be indispensable to obtain checks and resort futures to keep the injuries at this level.In the knowledge base mark tolerant if ALARP shows the welkin that the risk of injury to those involved in the process ahs increased, if the risk was under taken conse quently there could be a benefit. This can be lowly into 2 yet subsections, if the frequence is low the it can be passable if the toll of the risk reduction exceeds the improvement, as the frequency increases then it would lonesome(prenominal) be tolerable if the risk reduction is unwieldy or the cost disproportionate to the gains in improvement.The subject field shaded bitter is the area where the frequency is at it highest and therefore the risk cannot be warrant unless in obnoxious circumstances, for example running(a) on a live high potency galvanising system. research 4 defer 4. 4 in cease 3 fall apart 4 shows the discordant lay outs in naught metempsychosis for fuel use to magnate a computer. It shows a hypothetical equilibrium canvas tent for competency rebirth from chemical nada (in a fuel) to dismay aptitude (light emitted by a computer display). a) The truth of vitality conference states that force may incomplete be created nor destroye d but modify into antithetical forms of vim i. . to heat, light, or upset aptitude. therefore the sum of all the energies in the system is a constant. excuse curtly the formula of the conservation of vim, and how it applies at each stage in the aptitude rebirth process.
