Course Description

Covers measurements and calculations used in industrial and commercial facilities settings. Includes linear and volume measurement methods using analog and digital tools and instruments including rulers, calipers, micrometers, and dial indicators. Focuses on the use of fractions, decimals, powers, roots, algebraic equations, geometry, and right angle trigonometry to perform calculations for equipment repair, maintenance, installation, and operation. Prerequisites: MTH 20 or completion of any course for which it is a prerequisite. Audit available.

Addendum to Course Description

Required course for Apprentices registered in the Millwright/Industrial Maintenance Technician Apprenticeship Program. It is open to any other student but requires Department Permission to take this course.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  • Obtain and record measurements in facilities and industrial settings using a variety of measuring instruments in order to repair, maintain, install and operate mechanical equipment.
  • Calculate areas, volumes, lengths, angles, speeds, velocities, pressures, temperatures, volts, amps, ohms, and watts in facilities and industrial settings in order to repair, maintain, install, and operate mechanical equipment.
  • *Calculate elementary algebraic equations and formulas (*required statewide outcome).
  • *Apply appropriate formulas to mathematical situations (*required statewide outcome).

Course Activities and Design

The course design is primarily lecture with emphasis on measurements and calculations that apply to real-world scenarios in Facilities and Industrial settings which are relevant to repair, maintenance, installation and operation of equipment.

Course activities include:

  • Calculating areas and volumes
  • Calculating speed and velocity
  • Calculating pressures and temperatures and their relationship
  • Ohm's Law calculations
  • Application of a variety of measuring instruments to calculations
  • Using a hand held calculator
