Technical reasoning: applied practice: open practice pack: answer key

20 untimed questions across 4 authored sections.

This is untimed educational practice for one applied skill. It is not a clinical, diagnostic, employment, or professionally recognized assessment, it does not produce a score or credential, and for the judgement and safety families it is not a substitute for your employer's own policies, training, or legal duties.

technical-reasoning-applied-s01-q01DA vernier caliper
technical-reasoning-applied-s01-q02BTightening a fastener to a specified torque so the clamping force is correct and repeatable
technical-reasoning-applied-s01-q03CThe thread pitch: the distance between adjacent crests, in millimetres
technical-reasoning-applied-s01-q04AIt spreads the clamping load over a larger area and protects the surface finish
technical-reasoning-applied-s01-q05B20.03 mm
technical-reasoning-applied-s02-q01CA reference dimension, given for information and not to be worked or inspected to
technical-reasoning-applied-s02-q02A200 mm
technical-reasoning-applied-s02-q03DA line of short evenly spaced dashes
technical-reasoning-applied-s02-q04BTo the right of the front view
technical-reasoning-applied-s02-q05DIt does not meet the specification: at the stated duty point it delivers only 38 L/min
technical-reasoning-applied-s03-q01AWhether the drive train is jammed or a coupling has failed, since the motor is clearly receiving power
technical-reasoning-applied-s03-q02DEach test eliminates half of the remaining suspect area, so the fault is located in far fewer tests
technical-reasoning-applied-s03-q03BThe gauge or its isolating valve is at fault, because the ram lifting its load proves pressure exists
technical-reasoning-applied-s03-q04CSomething whose behaviour changes with temperature, such as a loose terminal expanding or a marginal component drifting
technical-reasoning-applied-s03-q05ARe-test under the conditions that produced the fault, confirm the symptom is gone, and record what was found and done
technical-reasoning-applied-s04-q01BThe work happens at a chosen time, which reduces unplanned downtime and the consequential damage a failure causes
technical-reasoning-applied-s04-q02CA clearance fit
technical-reasoning-applied-s04-q03AViscosity decides whether a film thick enough to separate the surfaces survives at the operating temperature and load
technical-reasoning-applied-s04-q04DThe aluminium corrodes preferentially at the joint, so the two metals are separated by an insulating washer or coating
technical-reasoning-applied-s04-q05CIt was fitted with the wrong preload, or the housing and shaft are misaligned
