Sort a scenario into one of those three behaviors, and most material questions answer themselves.<\/p>\n\n\n\n<p><strong>Work Mathematics II piece by piece.<\/strong> A piecewise function is several separate functions stitched together at boundary points. Identify which piece applies to the value the question asks about first, and check continuity and differentiability only at the join points.<\/p>\n\n\n\n<p><strong>Keep the Rankine cycle stages in strict order.<\/strong> Pump, boiler, turbine, condenser. Know which stage changes pressure, which changes phase, and which does both, and locate where in that sequence the question is asking.<\/p>\n\n\n\n<p><strong>Use the passage&#8217;s numbers rather than recalling your own.<\/strong> Substituting a half-remembered textbook constant instead of the passage&#8217;s stated value is a common way to lose easy marks.<\/p>\n\n\n\n<p><strong>Pace yourself across all five disciplines.<\/strong> With 90 minutes for the whole subject test, mechanical engineering is one fifth of your time budget, not the whole exam.

engineering divide into three families based on how they behave when heated. Thermoplastics turn soft somewhere in the range of about 80 to 160 degrees Celsius, at which point they can be reshaped completely; once cooled they hold the new shape, but heating them again undoes it. Thermosets are set hard from the start and stay hard even at raised temperature: they will not melt, burn or fuse to another piece, and past a certain temperature they simply decompose rather than soften. The only way to change a finished thermoset part is by machining it, in the same way a woodworker shapes timber. Elastomers behave differently again: squeeze or stretch one and it deforms briefly, then springs back to its original form the moment the load is removed. They resist most solvents and do not go soft on heating. <strong>Questions 1 to 3 refer to this input.<\/strong><\/p><table class=\"dme-t\"><tr><th>Family<\/th><th>Response to heat<\/th><th>How it is reshaped<\/th><\/tr><tr><td>Thermoplastics<\/td><td>Softens near 80 to 160 degrees Celsius<\/td><td>Remoulded, repeatedly<\/td><\/tr><tr><td>Thermosets<\/td><td>Stays hard, then decomposes<\/td><td>Machined only<\/td><\/tr><tr><td>Elastomers<\/td><td>Does not soften<\/td><td>Recovers its own shape<\/td><\/tr><\/table><\/div>\n<div class=\"dme-q\">\n<div class=\"dme-qtop\">\n<p class=\"dme-qlabel\">Question 1 <span class=\"dme-pill dme-pl\">Easy<\/span><\/p>\n<p class=\"dme-qtext\">A moulded plastic bracket needs to be melted down and recast into a different shape after use.

A few questions usually narrow the choice: does the part see a load that must spring back afterwards, or a load that should hold a new shape permanently? Will it meet heat that reaches a thermoplastic's softening range? Does the application call for the part to be remoulded or recycled by heating, or machined to its final size instead? As a rough guide, elastomers suit seals and cushioning, thermoplastics suit housings and parts that may need reshaping or recycling, and thermosets suit structural parts that must keep their strength at higher service temperatures. <strong>Questions 4 to 6 refer to this input.<\/strong><\/p><\/div>\n<div class=\"dme-q\">\n<div class=\"dme-qtop\">\n<p class=\"dme-qlabel\">Question 4 <span class=\"dme-pill dme-pl\">Easy<\/span><\/p>\n<p class=\"dme-qtext\">A manufacturer wants to injection mould thousands of identical clips and later regrind the sprue waste to mould more clips.

In polymerisation, monomers carrying a double bond are opened up under heat and pressure, usually with a catalyst, and join directly into a chain with no other substance given off. In polycondensation, monomers with reactive end groups link together step by step, and a small molecule, most often water, is released at each link as the chain grows. In polyaddition, monomers with reactive groups also join step by step, but without releasing a by-product molecule; atoms simply rearrange, often as a hydrogen atom migrates from one monomer to the next, as the chain forms. <strong>Questions 7 to 9 refer to this input.<\/strong><\/p><table class=\"dme-t\"><tr><th>Route<\/th><th>By-product released<\/th><th>Example<\/th><\/tr><tr><td>Polymerisation<\/td><td>None<\/td><td>Polyethylene from ethylene<\/td><\/tr><tr><td>Polycondensation<\/td><td>Small molecule, often water<\/td><td>Polyester from an acid and an alcohol<\/td><\/tr><tr><td>Polyaddition<\/td><td>None, but atoms rearrange<\/td><td>Polyurethane from a diisocyanate and a polyol<\/td><\/tr><\/table><\/div>\n<div class=\"dme-q\">\n<div class=\"dme-qtop\">\n<p class=\"dme-qlabel\">Question 7 <span class=\"dme-pill dme-pl\">Easy<\/span><\/p>\n<p class=\"dme-qtext\">Which production route releases water as a by-product at every step of chain growth?<\/p>\n<ul class=\"dme-opts\" data-a=\"2\"><li role=\"button\" tabindex=\"0\"><b>a)<\/b> Polymerisation<\/li><li role=\"button\" tabindex=\"0\"><b>b)<\/b> Polyaddition<\/li><li role=\"button\" tabindex=\"0\"><b>c)<\/b> Polycondensation<\/li><li role=\"button\" tabindex=\"0\"><b>d)<\/b> None of the three<\/li><\/ul>\n<div class=\"dme-fb\" aria-live=\"polite\"><\/div>\n<\/div>\n<details class=\"dme-sol\">\n<summary><span class=\"dme-st\"><span class=\"dme-spark\">&#10022;<\/span><span><span class=\"dme-sv\">View Solution Path<\/span><span class=\"dme-sh\">Hide Solution Path<\/span><\/span><\/span><span class=\"dme-chev\">&#9660;<\/span><\/summary>\n<div class=\"dme-solb\"><p><strong>Answer: c.<\/strong> Polycondensation joins monomers with reactive end groups step by step, and at every new link a small molecule, typically water, is released as a by-product.

First, a pump raises the pressure of the liquid working fluid with very little temperature rise. Second, the pressurised liquid absorbs heat at constant pressure in a boiler, turning into vapour. Third, the vapour expands through a turbine, giving up energy as it drives the shaft and dropping in pressure and temperature. Fourth, the low-pressure vapour is cooled at constant pressure in a condenser, returning to liquid so the cycle can repeat. Cycle efficiency depends on how much heat is added at high temperature against how much is rejected at low temperature during condensation. The same principle of moving heat through a working fluid, and rejecting it efficiently at the low-temperature end, is what makes thermal management such a central concern in battery pack design. <strong>Questions 10 to 12 refer to this input.<\/strong><\/p><table class=\"dme-t\"><tr><th>Stage<\/th><th>What happens<\/th><th>Fluid state change<\/th><\/tr><tr><td>1: Pump<\/td><td>Pressure raised<\/td><td>Liquid, at higher pressure<\/td><\/tr><tr><td>2: Boiler<\/td><td>Heat added at constant pressure<\/td><td>Liquid to vapour<\/td><\/tr><tr><td>3: Turbine<\/td><td>Vapour expands, work extracted<\/td><td>Pressure and temperature fall<\/td><\/tr><tr><td>4: Condenser<\/td><td>Heat rejected at constant pressure<\/td><td>Vapour to liquid<\/td><\/tr><\/table><\/div>\n<div class=\"dme-q\">\n<div class=\"dme-qtop\">\n<p class=\"dme-qlabel\">Question 10 <span class=\"dme-pill dme-pl\">Easy<\/span><\/p>\n<p class=\"dme-qtext\">In which stage of the Rankine cycle does the working fluid change from liquid to vapour?<\/p>\n<ul class=\"dme-opts\" data-a=\"1\"><li role=\"button\" tabindex=\"0\"><b>a)<\/b> The pump<\/li><li role=\"button\" tabindex=\"0\"><b>b)<\/b> The boiler<\/li><li role=\"button\" tabindex=\"0\"><b>c)<\/b> The turbine<\/li><li role=\"button\" tabindex=\"0\"><b>d)<\/b> The condenser<\/li><\/ul>\n<div class=\"dme-fb\" aria-live=\"polite\"><\/div>\n<\/div>\n<details class=\"dme-sol\">\n<summary><span class=\"dme-st\"><span class=\"dme-spark\">&#10022;<\/span><span><span class=\"dme-sv\">View Solution Path<\/span><span class=\"dme-sh\">Hide Solution Path<\/span><\/span><\/span><span class=\"dme-chev\">&#9660;<\/span><\/summary>\n<div class=\"dme-solb\"><p><strong>Answer: b.<\/strong> The passage places the phase change from liquid to vapour in the boiler, where the pressurised liquid absorbs heat at constant pressure until it becomes vapour.
