Trigonometry in mechanical engineering

Quick Look

Units serve as guides to a specific content or topic area. Nested under units are lessons (in purple) and also manual tasks (in blue).

Keep in mind that not all lessons and activities will certainly exist under a unit, and rather might exist as "standalone" curriculum.


Unit circle for trigonometry.

Some objects and also ranges in our human being are extremely difficult—also impossible—to directly measure by hand also or with tools. Engineers who design different types of structures, either incredibly big or very tiny, or machines, which might take a trip distances deep under the sea or far right into space, need to have actually an accurate expertise of lengths and also dimensions, even once they cannot be measured. Often in these instances, designers usage trigonometry and also various other mathematical relationships to uncover incredibly close approximations to lengths and dimensions. In the architecture of big frameworks, engineers must encertain that forces acting on the framework will certainly balance so that they reprimary stationary. Engineers use trigonomeattempt to account for vertical and horizontal components of the various pressures that act on structures, thus determining that the structure will certainly have the ability to stand also without collapsing prior to it is also created. These strategies, based on mathematical expertise, permit engineers to design remedies to troubles that could otherwise be unsolvable.

Learning Objectives

After this leskid, students need to be able to:

Describe just how a clinometer have the right to be supplied by engineers.Use a clinometer to measure angles.

Educational Standards

Each leschild or task is associated to one or more K-12 scientific research, innovation, design or math (STEM) educational standards.

All 100,000+ K-12 STEM standards spanned in are gathered, preserved and packaged by the Achievement Standards Netjob-related (ASN), a task of D2L (

In the ASN, requirements are hierarchically structured: initially by source; e.g., by state; within source by type; e.g., science or mathematics; within form by subkind, then by grade, etc.
