Students view the formula for determining twist drill speeds in metal.

This document is a visual and text description of Calculating Turning Speeds & Feeds on a lathe.

Learners review the process for calculating board feet and use virtual samples to practice the process.

In this learning activity you'll calculate exponents. You'll practice breaking down exponents and calculating the results.

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 interactive object, learners calculate formula and molecular weights by working through five examples and two problems.

In this learning activity you'll calculate the determinant of a 2x2 matrix.

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.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.

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.

In this screencast, learners follow steps to determine the proper starting belt length for a timing, flat, or v-belt drive.

In this interactive object, learners are given the RPM, the pulley diameter, and the force, and proceed to calculate belt velocity and horsepower.

In this animated activity, learners view the seven steps that are used to calculate voltage and current values throughout a common-emitter transistor amplifier.

This video will walk through how to calculate speeds and feeds for drilling parts on a milling machine.

In this animated and interactive object, learners examine the formula for horsepower and work practice problems.

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.

Students read how to calculate feed rates for drills in inches per minute (IPM). The IPM formula is given and students work two practice problems.

In this learning object the student will learn how to measure a stain and calculate angles of impact. Determining the angle of impact for bloodstains takes advantage of the trigonometric functions (Sine function).

A mathematical relationship exists between the width and length of an elliptical bloodstain which allows for the calculation of the angle of the impact for the original spherical drop of blood.

Given well formed stains we can accurately measure the width and length by simply dividing the stain along it’s major and minor axis. The opposite halves would be generally equal to each other which aids in establishing the impact angle.
