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.
Learners explore the use of complex numbers through a series AC circuit analysis problem. The steps are compared to the graphical method of finding circuit impedance and the phase angle.
In this screencast, the student will learn that regardless of the surface onto which a blood droplet is falling, the angle or velocity at which it does so, or the volume of the droplet, there are four distinct phases involved in the reaction of a moving droplet with impact against a surface.
In this teaching and learning aid, the user can alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.
The learner reads an explanation of how to determine lengths for tubing and pipe bending and then performs calculations in an interactive exercise. Two methods for determining angle bends are shown. A calculator is required.
In this animated activity, learners read about the properties of a rectangle and its components. They then work practice problems to find the perimeter and area of rectangles.
Learners view a vector diagram for a series RL circuit. Information on the voltage across each component, the total voltage, and the phase angle is included.
Learners read about the vector diagram for a parallel RL circuit. This animated lesson presents information on current flow through each branch, total current, and phase angle.
