Reciprocating mass

This paper offers a supplementary explanation that mass media facilitated the diffusion of contraceptive knowledge, leading to an ideological shift to value small families, and social networks especially reciprocal encouragement about contraception practice among network members has helped to sustain this shift.

The torsional vibration phenomenon in the running gear of reciprocating engine systems is usually dealt with by considering a series of constant inertias connected by sections of massless shafting. However in reality, a slider crank mechanism is a vibrating system with varying inertia because the effective inertia of the total oscillating mass of each crank assembly varies twice per revolution of the crankshaft.

Chapter 4 - Energy analysis of closed systems. The objectives of Chapter 4 are to: Examine the moving boundary work or P dV work commonly encountered in reciprocating devices such as automotive engines and compressors, identify the first law of thermodynamics as simply a statement of the conservation of energy principle for closed (fixed mass) systems, develop the general energy balance applied to closed systems,...

The following chapters discuss architects who have honed digital-fabrication techniques on pecific projects. Each discussion is accompanied by a detailed breakdown of the fabrication technique, providing insight into the recent projects featured in ach chapter. These are projects that concentrate on he fertile realm of one-to-one-scale experimentation, which demands reciprocity between design and mpirical innovation. The final outcomes hinge on he ability to reconcile the developmental shifts in material and working method.
