Brachistochronous motion of a flat plate parallel to its surface immersed in a fluid
S. Mandre
We determine the globally minimum time needed to translate a thin submerged flat plate a given distance parallel to its surface within a work budget. The Reynolds number for th…
How to run on rough terrains
Nihav Dhawale, Shreyas Mandre, Madhusudhan Venkadesan
Stability of running on rough terrain depends on the propagation of perturbations due to the ground. We consider stability within the sagittal plane and model the dynamics of runni…
Surface tension of flowing soap films
Aakash Sane, Shreyas Mandre, Ildoo Kim
The surface tension of flowing soap films is measured with respect to the film thickness and the concentration of soap solution. We perform this measurement by measuring the curvat…
Transverse contributions to the longitudinal stiffness of the human foot
Ali Yawar, Lucia Korpas, Shreyas Mandre +1
Humans rely on foot stiffness to withstand the propulsive forces of walking and running. Skeletal adaptations that increase foot stiffness include the medial longitudinal arch (MLA…
Stiffness of the human foot and evolution of the transverse arch
Madhusudhan Venkadesan, Marcelo A. Dias, Dhiraj K. Singh +2
Foot stiffness underlies its mechanical function, and is central to the evolution of human bipedal locomotion. The stiff and propulsive human foot has two distinct arches, the long…
Hydrodynamic signatures of stationary Marangoni-driven surfactant transport
S. Mandre, V. S. Akella, D. K. Singh +2
We experimentally study steady Marangoni-driven surfactant transport on the interface of a deep water layer. Using hydrodynamic measurements, and without using any knowledge of the…
