Two blocks with masses m 1 and m 2, respectively, are connected via a massless thread over a pulley wheel. The wheel is a solid, uniform disk with mass m 3, outer radius R, and a frictionless axle. Initially you hold m 2 (and therefore the entire system) at rest in the position shown; m 2 is at rest on level ground. Then you release m 2. The ...

Emergency advance paymentFor a less trivial example, consider two point-like objects with masses m 1, m 2, attached to the ends of a rigid massless bar with length 2R, the assembly being free to rotate and slide over a fixed plane. The state of the system can be described by the generalized coordinate vector

Jan 01, 2013 · In the subsequent sections, an analytical model will be established for a graded continuum rod by using the shock theory. Two impact scenarios are considered. Scenario I is the same as the above FE simulations, in which a stationary rod is impinged by a rigid mass. In Scenario II, the rod together with an attached mass impinges onto a rigid ...
