Franck-Hertz Experiment
Electrons are accelerated by applying a known potential between two grids inside the argon tube. When an electron has sufficient kinetic energy to excite...
Four-Point Bending
A Four-Point Bend Test is performed on plastic beams as shown in Figure 1. As a downward force (F) is applied in the middle of the beam, the flex (Δx)...
Three-Point Bending
A Three-Point Bend test is performed on a round rod as shown in Figure 1. As a downward force (F) is applied in the middle of the rod, the flex (Δx) is...
Column Buckling and the Euler Column Equation
The Euler Column Equation predicts the maximum compressional force applied to a column before it...
Column Buckling and Slenderness Ratio
Three different length plastic I-beams are tested under compression to investigate their method of...
Physical Pendulum Period and Inertia
This experiment has two parts: 1. Period of a Thin Rod explores the dependence of the period of a physical pendulum (a uniform bar) on the distance between...
Heat Engine Cycle - Wireless
A P-V diagram is generated as a heat engine is taken through a cycle. From this diagram, the heat added to the gas and the work done by the engine are...
Faraday's Law of Induction - Wireless
A voltage is induced in a coil swinging through a magnetic field. Faraday's Law and Lenz' Law are...
Interference and Diffraction - Wireless
Interference and diffraction patterns from laser light passing through various single-slits and multiple-slits...
Conservation of Energy II - Wireless
A ball is dropped from rest and its height and speed are recorded using a Wireless Motion Sensor. The ball’s potential energy and kinetic energy are...
