"Walking" Along a Free Rotating Bicycle Wheel (Round and Round)
Julio Guemez, Manuel Fiolhais
We describe the kinematics, dynamics and also some energetic issues related to the Marta mouse motion when she walks on top of a horizontal bicycle wheel, which is free to rotate l…
Dissipation effects in mechanics and thermodynamics
Julio Guemez, Manuel Fiolhais
With the discussion of three examples, we aim at clarifying the concept of energy transfer associated with dissipation in mechanics and in thermodynamics. The dissipation effects d…
Thermodynamics in rotating systems -- analysis of selected examples
Julio Güémez, Manuel Fiolhais
We solve a set of selected exercises on rotational motion requiring a mechanical and thermodynamical analysis. When non-conservative forces or thermal effects are present, a comple…
Thermodynamical asymmetries in whirling, jumping and walking
Julio Güémez, Manuel Fiolhais
We analyze, from the thermodynamical point of view, mechanical systems in which there is production of mechanical energy due to an internal source of energy, and compare that analy…
A 4-vector formalism for classical mechanics
Julio Güémez, Manuel Fiolhais
We present a matrix formalism, inspired by the Minkowski four-vectors of special relativity, useful to solve classical physics problems related to both mechanics and thermodynamics…
