On the Stability of Four Legged Tables
نویسنده
چکیده
We prove that a perfect square table with four legs, placed on continuous irregular ground with a local slope of at most 15 degrees can be put into equilibrium on the ground by a " rotation " of less than 90 degrees. We also discuss the case of non-square tables and make the conjecture that equilibrium can be found if the four feet lie on a circle.

We prove that a perfect square table with four legs, placed on continuous irregular ground with a local slope of at most 14.4 degrees and later 35 degrees, can be put into equilibrium on the ground by a " rotation " of less than 90 degrees. We also discuss the case of non-square tables and make the conjecture that equilibrium can be found if the four feet lie on a circle.

متن کاملA Novel Six Wheel-legged Robot: Structure Design and Stability Analysis in Different Typical Gaits
Wheel-legged robot which combines the advantages of wheeled robot and legged robot can be better adapted to complex environment. Increasing the operation function of the robot is one of the hottest topics in this field. A novel six wheel-legged robot is designed in the form of leg structure, body structure and the combination between wheels and legs. The DOF of single leg and multi-legged close...
متن کاملSeismic Response of 4-Legged Self-Supporting Telecommunication Towers
Telecommunication tower is an important component of the basic infrastructure of communication systems and thus preserving them in events of natural disasters - such as a severe earthquake - is of high priority. In past studies, researchers have mostly considered the effects of wind and earthquake-induced loads on 3-legged (triangular cross-section) self-supporting steel telecommunication tower...
