WebSeventh Vector Mechanics for Engineers: Dynamics Edition 18 - 49 Sample Problem 11.3 Brake mechanism used to reduce gun recoil consists of piston attached to barrel moving in fixed cylinder filled with oil. As barrel recoils with initial velocity v0, piston moves and oil is forced through orifices in piston, causing piston and WebApr 12, 2006 · A one-dimensional piston problem of gasdynamics - Volume 85 Issue 1. This paper considers the case of a one-dimensional piston moving outwards with a speed proportional to r α and driving a strong shock into a non-uniform ambient gas whose density is initially proportional to r −k, k > 0.This problem is connected with that studied by …
