This learning object introduces the student to the calculations involved in a sieve analysis -- including percentage retained and percentage passed.

Students read how to determine the elevation of an alignment or cross section where it crosses the TIN.

In this animated object, learners examine how to establish an effective supply chain that builds customer loyalty.

Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

Students view the steps for dividing complex numbers in Excel.

Students read how to lock a cell that is being referenced in a formula so that it does not automatically show an increment when the formula is copied.

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.

Learners examine the use of the tolerances displayed in a title block by calculating the minimum and maximum allowable size of a fabricated part. In a brief quiz, students determine whether a part is usable or should be scrapped.

In this animated object, learners examine what happens to lead and cycle times when the batch size is reduced.

Students follow the correct keystrokes to calculate the logarithm of a number.

In this interactive object, learners read the common abbreviations used in engineering drawings and then test their knowledge in three short exercises.

Students read how to use the IMCONJUGATE() function to convert complex numbers to their conjugate in rectangular form.

In this animated activity, students read about weight-volume relationships within a given sample of soil or aggregate. They complete problems using a 3-phase diagram.

Learners view examples of devices that prevent mistakes from occurring.

Learners examine the complex number function to convert real and imaginary coefficients into a complex number.

Learners examine ways to eliminate or minimize the wastes found in business processes. A matching exercise completes the activity.

In this interactive and animated object, learners apply the Law of Sines to determine forces using a TI-86 calculator.

Learners follow step-by-step instructions for calculating the square root of a number using the TI-83 Plus scientific calculator. Steps for determining impedance are also shown.

In this interactive object, learners use the Law of Cosines to calculate forces.

This learning object introduces the student to sieves and how their designation is related to the aggregate size.

Students read how to use the DEGREES() function to convert radians to degrees.

Learners examine how to solve problems using the Pythagorean Theorem in Excel. Practice problems are included.

In this animated object, learners read the dimensions of the different types of vehicles typically considered in highway design.

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.

In this interactive object, learners read a description of value-added and non-value-added activities and then place various work duties into these two categories.
