In this animated and interactive object, learners calculate the maximum velocity of the work stroke and the return stroke.
By Tim Tewalt, Patrick Hoppe
In this animated object, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.
PLC Counter Operation
By Terry Bartelt, Tom Yapp
Learners examine the two methods used by programmable logic controllers to perform a counting operation using addition or counter instructions. A brief quiz completes the activity.
By Terry Bartelt
Learners examine how air-to-open valves and air-to-close valves are used in different situations. A brief quiz completes the activity.
Kirchhoff's Voltage Law with Complex Numbers
By Patrick Hoppe
Learners view a demonstration of Kirchhoff's Voltage Law using complex numbers for an ac circuit.
Identifying Lever Classes
By James Bourassa
In this interactive object, learners read an introduction to Class 1, Class 2, and Class 3 levers and then take a quiz.
Calculating Horsepower, RPM, and Torque
By James Bourassa, John Rosz
In this animated and interactive object, learners examine the formula for horsepower and work practice problems.
Orthographic Projection #1
By Glenn Sokolowski
In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.
Brain Exercise: Visualization #1
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.
Brain Exercise: Visualization #3
Learners develop 3D visualization skills by examining front, side, and top orthographic views of objects. Using this information, students select the corresponding isometric view of each object.
