The medium/heavy truck technician must be proficient in the following Mathematics Related Academic
Skills that are embedded in the occupation. Given these skills the technician must be able to:
Determine the proper sequence of arithmetic operations to arrive at a solution to a problem that can be compared to other specifications when comparing system measurements to the manufacturer's specifications.
Add two or more whole numbers, fractions, or decimals to determine component conformance of multiple measurements with the manufacturer's specifications of the truck or trailer.
Subtract whole numbers, fractions, or decimals to arrive at a difference for comparison with the truck manufacturer's specifications.
Divide decimals to determine measurement conformance with the truck manufacturer's
specifications.
Convert variables presented orally to a mathematical form that provides for an algebraic solution.
Estimate the results of basic arithmetic operations, and accurately round up or down depending on the appropriate rule for the situation.
Analyze and solve problems requiring the use of fractions, decimals, ratios, or percentages by a direct or indirect variation of the numerical elements of the problem.
Determine the irrelevant or missing data needed to solve a problem.
Determine and interpret place value (tenths, hundredths, thousandths) when conducting precision measurements.
Use Centigrade or Fahrenheit measurement scales to determine the existing temperature of substances such as a coolant or lubricant.
Use English and metric volume measurement techniques to determine the volume of a system, component, or cylinder.
Use conventional symbols (E for voltage, etc.) to solve circuit parameter calculations using formulas such as Ohm's Law, E=IR.
Understand that if the described problem has certain conditions (symptoms), then a limited number of solutions to the problem apply.
Understand the relationship between the frequency of the occurrence of a problem (symptom) and the probability of accurately predicting the problem.
Calculate the average (mean) of several measurements to determine the variance from the manufacturer's specifications.
Use English and metric angle and distance measurements and techniques to determine angle variances from the truck manufacturer's specifications.
Solve problems that involve determining the relative proportion of desired versus undesired ingredients or elements of a mixture, and determine if that proportion is within the manufacturer's specifications.
Comprehend and use standards defined by each manufacturer for the system being analyzed.
Convert test readings that are in decimal or fraction form to a ratio or percent for comparison with the manufacturer's specifications for the sub-system.
Know when to use an estimated performance value versus an exact value, basing the decision on the system being analyzed or repaired.
Visually perceive the geometric relationship of systems and sub-systems that require alignment.
Construct or interpret a chart, table, graph, or symbol that depicts a range of performance characteristics that can be used for comparing various system operational conditions.
Use precision measurement devices to determine the parallelism or perpendicularity of chassis, suspension, and other vehicle components requiring geometric alignment.
Use formulas to indirectly confirm systems that are outside of the manufacturer's specifications.
Verify that the relationship between parallel lines and angles concurs with the manufacturer's specifications when diagnosing a system's malfunction.
Visually formulate an angle (e.g. belt/suspension/drive) and verify conformance to the manufacturer's specified angle.
Measure timed or sequenced operating parameters to determine conformance with the
manufacturer's specifications of the truck.
Use English and metric scales to determine the conformance of components to the manufacturer's specified weight of the truck.
Determine the degree of conformance to the manufacturer's specifications for length, volume, and other appropriate measurements in the English and metric system.
Distinguish the congruence of the measured tolerances with those specified by the manufacturer.
Measure and test with tools designed for English or metric measurements, then convert the result to the manufacturer's system used for specifying the correct measurement or tolerance.
Compute mentally whether the observed measurement is out-of-tolerance when comparing the observed measurement to the manufacturer's specifications.
Solve problems that involve determining whether the proportion of the existing volume compares to the manufacturer's specifications and is within the recommended tolerance.
Distinguish whether a measurement or tolerance is equal or not equal to the manufacturer's specifications.
Solve basic and complex algebraic expressions.
