Learners read a description of torque and study the factors that cause its magnitude to change.
Capacitive Reactance Practice Problems
By Patrick Hoppe
Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.
Physics Concepts in Hydraulics
By Terry Bartelt
In this animated activity, learners view the following physics concepts in action: force, friction, horsepower, work, power, inefficiency, resistance, inertia, and energy.
The 555 Monostable Multivibrator
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.
Series-Parallel Circuit Analysis: Practice Problems Circuit 1
In this interactive object, learners analyze a series-parallel DC circuit problem in a series of steps. Immediate feedback is provided.
What Is Torque?
Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
Calculating Board Feet
By Patrick Molzahn
Learners review the process for calculating board feet and use virtual samples to practice the process.
Using a Lumber Rule
Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.
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.
Introduction to Class 2 Levers
