Learners examine how a linear displacement transducer is used to measure the linear position of a physical object. Animations show the sequential steps of the entire operation.

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

Students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.

In a series of practice problems, learners use the addition or subtraction method to solve systems of linear equations, also called "simultaneous linear equations."

In a series of practice problems, learners use the substitution method to solve systems of linear equations, also called "simultaneous linear equations."

Learners study how a circuit converts the AC output of a linear voltage differential transformer (LVDT) into variable DC voltage. It is recommended that learners view the learning object IAU7807, “The LVDT: A Linear Voltage Differential Transformer in Action” before going through this object.

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.

The learner will identify the types of motion instructions used for programming a robot.

In this learning activity you'll test your knowledge of the different types of steel rules as well as how to use and read them correctly.

Learners examine a 555 integrated circuit, which functions as a one-shot monostable multivibrator, and then test their knowledge. Immediate feedback is provided. Animations are used to show the sequential operations.

In this animated object, learners examine the situation that occurs when any two links of a mechanism lie in the same plane or on a straight line. Crank-sliders and crank-rockers are shown.

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 identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.

In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.

In this screencast, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations.

In this learning activity you'll solve systems of two linear equations in two unknowns by determinants.

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

In this animated and interactive object, learners observe how two, three, or four groups of electrons around the central atom cause the shape of the molecule to be linear, trigonal planar, bent, tetrahedral, or pyramidal. Seven examples and eight interactive questions are provided.

Learners examine how five or six groups of electrons around a central atom cause the shape of the molecule to be trigonal bipyramidal, seesaw, T-shaped, linear, octahedral, square pyramidal, or square planar. Seven examples and three interactive questions are provided in this animated activity.
