An educational aid and educational system is provided that enables a seamless transition between theoretical teachings and practical demonstration. The educational aid comprises: a circuit component, including first and second terminals and a portion of a circuit there between; and a schematic of the portion of the circuit extending between the first and second terminals. The educational aid is configured to be coupled to other educational aids using the terminals, to simultaneously create a circuit and a corresponding schematic.

Model elements of an executable model, representing a physical system, are partitioned into one or more linear portions and one or more nonlinear portions. Simulating behavior of the physical system, by executing the model, includes, for each of multiple simulation time intervals, for a first nonlinear portion, computing a correlation matrix characterizing noise associated with one or more ports of the model. A scattering matrix corresponds to a portion of the physical system represented by the first nonlinear portion without accounting for any noise within the portion of the physical system. The correlation matrix is derived from the scattering matrix based on noise within the portion of the physical system. Noise sources representing noise within the portion of the physical system are identified based on the correlation matrix. At least one characteristic of noise associated with each noise source is computed, and noise characteristics are output at selected ports.

The educational system for teaching mechanical failure includes first and second specimen pieces. The first and second specimen pieces are adapted to be magnetically joined to one another at a selected magnitude of magnetic force. A linear force measuring device, such as a load cell, is secured to the first specimen piece and a support frame. A linear actuator is secured to the support frame and the second specimen piece to selectively apply a separation force to the first and second specimen pieces. In use, a user may increase a magnitude of the separation force until the first and second specimen pieces separate from one another. The measured separation force when the first and second specimen pieces separate from one another is representative of a required force to cause mechanical failure.
