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.

A data processing method for an analogue modelling experiment of a hypergravity geological structure includes steps of: performing two-dimensional photographing and three-dimensional elevation scanning with an analogue modelling experiment device with a curved model surface for the hypergravity geological structure, so as to collect initial elevation data and initial velocity field data; and correcting the initial elevation data and the initial velocity field data to obtain corrected elevation data and corrected velocity field data. The data processing method can realize orthographic correction and three-dimensional projection transformation of initial elevation data, as well as orthographic correction and two-dimensional projection transformation of initial velocity field data, which can more realistically and objectively reflect the experimental phenomenon, which is conducive to truly expressing the experimental results and facilitates the analogy analysis with the actual geological prototype.

A teaching system includes a CAD/CAM facility that features a CAD-generated crane boom design and a CAM-generated crane boom model based on the crane boom design. A simulator runs a simulation of the crane design using a finite element analysis (FEA) to evaluate the stress-strain performance of the crane design as a function of variable input parameters. The crane boom model is tested under various load and operating conditions to measure its behavioral response in terms of stress-strain behavior. A sensor array monitors the stress-strain behavior of the crane model during testing. The testing performance of the CAM-generated crane model is will allow a comparison with the FEA-based simulation results of the CAD/CAM generated crane design.

Described herein are wireless smart devices having integrated force, position, acceleration, and rotational sensing for science education (e.g., Newton's laws of motion, kinematics, etc.). An integrated wireless device includes an accelerometer to generate acceleration data based on detecting a current rate of acceleration of the integrated wireless device, a shaft encoder to detect angular positional changes of a shaft or axle of the integrated wireless device over time, and at least one processing unit coupled to the accelerometer.
