Anchor escapement is, an increase in amplitude of swing causes a slight increase in period of a pendulum due to circular error, and that this can compensate for the decreased period due to isochronism. Due to this effect a carefully adjusted anchor escapement with polished pallets might be more accurate than a deadbeat. This has been confirmed by at least one modern experiment. Anchor escapement In horology, the anchor escapement is a type of escapement used in pendulum clocks. The escapement is a mechanism in a mechanical clock that maintains the swing of the pendulum by giving it a small push each
Strain energy release rate a straight path, the mode I stress intensity factor (formula_10) is related to the energy release rate (formula_5) by where formula_13 is the Young's modulus and formula_14 for plane stress (as in a thin tensed elastic sheet) and formula_15 for plane strain (as in a thick elastic slab). Therefore, the energy release rate failure criterion may also be expressed as where formula_17 is the mode I fracture toughness. Strain energy release rate The strain energy release rate (or simply energy release rate) is the energy dissipated during fracture per unit of newly created fracture surface area. This quantity is central
