A common, yet hazardous, method of transporting cylindrical tanks used to carry compressed gas involves rolling both tanks at opposite angles of inclination to the vertical. By propelling one of the tanks while maintaining point contact between the tanks, both tanks can be moved such that their centers of mass move in a straight line as demonstrated in the video below:

Call for Proposals to Host the
2030 US National Congress on Theoretical & Applied Mechanics
The Department of Mechanical and Aerospace Engineering at the University of Houston (UH) invites applications for two Presidential Frontier Faculty positions at the rank of tenure-track Assistant Professor or tenured early Associate Professor, depending on the qualifications of the successful candidates, with appointments beginning in Fall 2025. The Presidential Frontier Faculty program at UH is a university-wide, integrated, interdisciplinary faculty hiring initiative designed to address pressing federal priorities and societal challenges.
The Nguyen Lab (nguyenlab.wse.jhu.edu) invites applications for a postdoctoral position in computational biomechanics with applications to ocular biomechanics. The postdoctoral scholar will be involved in an R01 funded project to study the relationship between the structure and mechanical properties of the optic nerve head tissues and remodeling with glaucoma. The project is highly interdisciplinary and involves long-standing collaborations between the Nguyen Lab and world-renowned glaucoma clinician-scientists at the Wilmer Eye I

The School of Civil and Environmental Engineering at Cornell University (Ithaca campus) invites applications for a tenure-track faculty position in the broad area of dynamics related to the mechanics of structures and materials. Our definition of structures is broad and includes buildings, bridges, dikes, wind turbines, and solar devices/solar panels.
We are interested in applicants whose research is related to any of the following or related areas:
• Material and/or structural response to dynamic loading arising from wind, waves, blast, seismic waves
Considerable research has been conducted on shape of pillar ends for optimal adhesion. In experiments with elastomers it has been found that mushrooms-ended ones are superior to flat-ended ones, but early experiments have suggested an extremely strong scaling in strength with pillar radius (del Campo et al Langmuir;23 :10235-43, 2007). We discuss various theories and experimental results on scaling of strength, and in particular we elaborate recent experiments on single pillars with mushroom ends finding that the scaling on strength is much less surprising.
