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. 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.
Consider a simple model for a rocket launched from the surface of the Earth. A better expression for a rocket’s position measured from the center of the Earth is given by:
where RE is the radius of the Earth (6.38 ✕ 106m) and g is the constant acceleration
of an object in free fall near the Earth’s surface (9.81 m/s2). Continue reading
Particles with two different masses m and M are located along a linear harmonic chain
of infinite length. The chain has a force constant k (see the picture below). The
distance between two particles with the same mass is equilibrium and equals to a.
qj and rj are the deviations of particles mj and Mj from their equilibrium positions respectively. Continue reading
The location of a solid particle of mass M is determined by the following equations:
X=A+Bt+C Y=D-Et+Fcos(Gt) Z=H+Fsin(Gt)
Where A…H are constants.
Determine the three components of the acceleration as a function of time. Does the time have influence on the direction and magnitude of the acceleration? Continue reading
