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.
You'll practice calculating the circumference of a circle given its diameter or radius.
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.
You'll practice finding the arc length, radius, or central angle of a circle when given the other two measurements.
You'll practice calculating the area of a circle given its diameter or radius.
You'll practice defining terms related to cones.
In this interactive object, students explore the basic elements and common terms associated with dimensions and leaders. A quiz completes the activity.
In this animated object, learners examine the bones of the appendicular skeleton.
In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
You'll practice calculating the surface area of a sphere.
You'll define terms related to circles.
You'll practice defining terms related to spheres and identifing parts of spheres.
The learner will use the ANSI Insert Identification System to identify and select carbide tools.
The learner will define indirect measurement, identify common indirect measuring tools, and select the proper measuring tool for the situation.
Students use trigonometry to find the coordinates of the blending point where a line and an arc meet. Learners are given the coordinates of the center of the arc, the radius of the arc, and the direction of the line.
In this animated and interactive object, learners examine the definitions and formulas for radius, diameter, circumference, and area. Students also solve practice problems involving the circumference and area of a circle.
