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.
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 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.
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.
