Students examine the procedure to measure current with an analog ammeter. The use of Function and Range switches is explored along with reading the needle position on the meter scale. A brief quiz completes the activity.
Learners follow procedures for measuring resistance using an analog ohmmeter. They examine the use of the Function Switch and the Range Switch and practice reading a non-linear scale. A brief quiz completes the activity.
Students follow the procedure to measure voltage with an analog voltmeter. They examine the use of the Function Switch and the Range Switch. A brief quiz completes the activity.
Basic Elements of Dimensions Used in Engineering Drawings
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
Basic Types of Dimensioning Used in Engineering Drawings
Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.
In this interactive object, learners practice their 3D visualization skills by identifying the correct isometric view of an object. Front, side, and top orthographic views are shown.
Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.
In this fourth part in a series, learners follow the steps of the “mathemagician” to examine three numerical curiosities: Be a Psychic by Predicting Birthdays, Predict a Card with Mind Reading, and Predict the Three Die Values Your Opponent Has Rolled. Learners will also study palindromic numbers and look at two alphametric puzzles.
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Learners examine the relationship of individual parts in an assembly drawing. Assembly drawing notes, fabricated and purchased parts, and sectional views are explained briefly.
Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.
Learners examine pictorial drawings used in engineering including sectioned and exploded drawings. A sketching quiz is provided to help the learner create simple pictorial sketches by using orthographic views and an isometric template.
