Hammers with optimal claw shape and method for development of optimally designed hammers, crowbars, and levers

摘要: A hammer-head comprising an optimally designed set of nail extraction claws oriented at a predetermined tangency angle relative to integrally mounted anvil. The is be used with integral or removable handle minimize the forces required in nails and exercising prying by such tools as common hammer, crowbar, lever stationary movable fulcrum point. An optimization methodology based on minimization energy implemented design algorithm for synthesis optimal contour shape claws. Boundary conditions, constraints, constitutive models, governing equations this are derived from length engagement conditions between nail, board, outcome facilitates single optimum claw range sizes, family contours varying ranges nails.
