Using the formula for elastic potential energy, we can calculate the energy stored in the rubber band: U = 0.5 * k * x^2. U = 0.5 * 90.8 N/m * (0.2 m)^2. U = 1.8 J. This means that the rubber band can store 1.8 Joules of elastic potential energy when stretched by 0.2 meters.

The downhill grade at which mechanical energy must no longer be generated occurs at approximately -9 deg, near the metabolically optimal running grade. At shallow uphill grades, mechanical energy must be generated to raise the CoM, and at steeper grades, additional energy must be generated to offset reduced elastic energy …
This paper presents a novel robot leg design. The leg is powered by a DC motor which drives elastic tendons to turn a foot. The tendons store elastic energy just as in nature. Preliminary experimental results show the leg has a well-defined resonance which can be exploited to produce hopping. We also offer a comparison of our leg with the cat hindlimb. …
ABSTRACT. The production of work by the contractile component (CC) and the storage and release of work in the elastic structures that act in series (the series elastic component, SEC) with the contractile component were measured using white muscle fibres from the dogfish Scyliorhinus canicula. Heat production was also measured because the …
Elastic energy refers to the potential energy stored in an object when it is deformed or stretched due to the application of a force. It is produced when an object undergoes elastic deformation, which means it can return to its original shape after the deforming force is removed. Objects possess elastic energy when they have the ability …
