Energy added with a sideways jolt to a bike running straight and upright (demonstrating self-stability) is converted into increased forward speed, not lost, as the oscillations die out. [2] A bike is a nonholonomic system because its outcome is path-dependent. In order to know its exact configuration, especially location, it is necessary to ...
A hydrocycle is a bicycle-like watercraft. The concept was known in the 1870s as a water velocipede [1] and the name was in use by the late 1890s. [2] Power is collected from the rider via a crank with pedals, as on a bicycle, and delivered to the water or the air via a propeller. [3]
Disadvantages include: Implementations to date are heavier than those of bicycle chain and sprocket designs.; Though some of the components in a sealed hydraulic system maintain constant efficiency upwards of 95% in all conditions (see hydristor), the overall losses usually result in an efficiency of about 75% (power loss of about 25%, see hydraulic machinery).
A speed test on water achieved an average speed of 1.12 m/s. The cyclist could transition the cycle in and out of the water while unassisted. This prototype has real applications in urban areas of flooding, as well as applications in the leisure industry. The Ocean Biker, Ebrahim Hemmatnia in his boat bike, March 2015, João Pessoa, Brazil.
A physical property is any property of a physical system that is measurable. [1] The changes in the physical properties of a system can be used to describe its changes between momentary states. A quantifiable physical property is called physical quantity. Measurable physical quantities are often referred to as observables.
