In this animated object, learners identify the basic parts and operation of a crank slider mechanism. They also follow the steps to use rotational input velocity to determine the linear output velocity of a slider component.
In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.
Learners consider the correct type of pushbutton to use as a Stop button, the way the Stop button should be hard wired, and the PLC input instruction to use. This animated object includes a short quiz. It is recommended that learners review the learning object “The PLC Examine-Off Instruction” before beginning this object.
Op Amp Fundamentals: The Transconductance Amplifier
Students read an introduction to the transconductance amplifier. They also view formulas for voltage-to-current conversion, closed-loop input, and output impedance. An example of how R1 controls the conversion factor is given.
