Theory of the elastic pianoforte hammer
Panchanon Das · Proceedings of the Physical Society · 1927
In previous Papers exact expressions have been obtained for the vibrations set up in a string by the impact of an inelastic and also of an elastic hammer. By making various approximations, the influence of which is examined in the Paper, formulæ are obtained from which it is easy to deduce the practical effect of the elasticity and velocity of the hammer, and of the position of its point of impact on the string.
