Learners examine dew point and the two types of humidity values, absolute and relative, along with the types of instruments used to measure them. The activity includes a video clip and a quiz.
Using Blueprints to Troubleshoot a Defective Compressor Motor
In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
Using Blueprints to Troubleshoot a Defective Water Pump
In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.
Temperature Emissivity of Non-Blackbodies (Screencast)
Learners study the effect of reflected and transmitted energy on the measurement of emitted energy by a non-blackbody. A short quiz completes the activity.
Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
Stain Measurement & Calculating Angles of Impact (Screencast)
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.
