Analytical and Experimental Study of a Variable-Mass Oscillator with Constant Mass Loss
Rod Milbrandt, Josep Ll. Suñer, Juan C. Castro-Palacio +2
We present an analytical and experimental study of a variable-mass oscillator with constant mass loss. Starting from the equation of motion of a spring-mass system whose mass decre…
Bringing Engineering into the Physics Lab: Exploring Crank-Slider Dynamics with Smartphones
Josep Ll. Suñer, Rod Milbrandt, Juan C. Castro-Palacio +3
Many of the students enrolled in the calculus-based physics sequence are pursuing engineering degrees. Lab activities that have a direct connection to engineering, analyzed with th…
Experimenting with RC and RL series circuits using smartphones as signal generators and oscilloscopes
Ives Torriente-García, Francisco M. Muñoz-Pérez, Arturo C. Marti +3
Simple, portable and low-cost experiments as RC and RL series circuits are proposed to experiment with DC circuits. Very common elements are used: a few electronics components (res…
Multiplexed vortex beam-based optical tweezers
Francisco M. Muñoz-Pérez, Vicente Ferrando, Walter D. Furlan +3
The design and implementation of a multiplexed spiral phase mask in an experimental optical tweezer setup are presented. This diffractive optical element allows the generation of m…
