Task: demonstrate the step-by-step creation and subsequent simulation of a double pendulum in MapleSim.
For this example, we will need the following components from the multibody library:
- the fixed frame component
- the rigid body frame component
- the revolute joint component
- the rigid body component
In this article we continue talking about Multisim software and its basic functionality (the previous part you can read in Guide #35). The good news for beginners is that you can accomplish most actions through menus and dialog boxes without having to actually learn all peculiarities of Multisim. Menus and dialog boxes are useful because they give you visual reminders of most options with each step of creating the circuit. In the long run, you will want to learn the program deeper, because this article is more about the basics. In the following article we will show you how to change component values, analyze components, use a multimeter, and more.
We advise all students who wish to use Multisim more efficiently to read this article. Also, don’t forget to check out the example of constructing a circuit in Multisim software (Guide #37). After you read this sample, your knowledge about Multisim software will help you create circuit schemes by yourself. Moreover, we have more articles and samples for engineering classes on our blog – check them out. You can also apply for homework assignment help online from us. Continue reading

Instead of moving back and forth, a conical pendulum moves in a circle at constant speed as its string traces out a cone (see figure below). One such pendulum is constructed with a string of length and bob of mass . The string makes an angle with the vertical.
An intrepid physics student decides to try bungee jumping. She obtains a cord that is m long and has a spring constant of . When fully suited, she has a mass of . She looks for a bridge to which she can tie the cord and step off. Determine the minimum height of the bridge L, that will allow her to stay dry (that is, so that she stops just before hitting the water below). Assume air resistance that is negligible.
