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.
Learners examine the drawing symbols used for counterbore, countersink, spotface, radius, diameter, and depth. In the quiz that completes the activity, they associate these symbols with machining applications.
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.
Building Core Abilities During Student Learning Through Formative and Summative Assessment
This learning object gives instructors an opportunity to review the definitions of formative and summative assessment and list examples of the evaluations they use. In a drag and drop exercise, they classify a variety of assessment tools as either formative or summative.
Calculating Bend Allowance for Press Brake Forming
Introduces two methods of determining bend allowance; one is simple and is an approximate, the other is more precise. Interactive part has learner calculate bend allowance and blank size.
Calculating Blank Size for Rolled Sheet Metal (Screencast)
In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.
Users calculate the tonnage required to punch holes in a specific base metal. The formula to be used is provided along with the tensile strength for various metals. A calculator is required.
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.
