3 Vibrating Systems
3.1 Mass–Spring System a) Free Vibration – Undamped Suppose a mass of M kilogram is placed on a spring of stiffness K newton‐metre (see Figure 2.5a), and the mass is allowed to sink down a distance d metres to its equilibrium position under its own weight Mg newtons, where g is the acceleration of gravity 9.81 m/s2. Taking forces and deflections to be positive upward gives (2.8)…

2 Simple Harmonic Motion
The motion of vibrating systems such as parts of machines, and the variation of sound pressure with time is often said to be simple harmonic. Let us examine what is meant by simple harmonic motion. Suppose a point P is revolving around an origin O with a constant angular velocity ω, as shown in Figure 2.1. If the vector OP is aligned in…

Vibration of Simple and Continuous Systems
1 Introduction The vibrations in machines and structures result in oscillatory motion that propagates in air and/or water and that is known as sound. The simplest type of oscillation in vibration and sound phenomena is known as simple harmonic motion, which can be shown to be sinusoidal in time. Simple harmonic motion is of academic…

Conclusions
What seemed like a luxury in the last century has now become necessity. Similarly, though automated vehicles may appear to be a luxury and a not-needed technology to some, they have the potential to radically change the lives of people around the world. There are some major challenges to bring this technology into existence. One…

Safety Concept for Autonomous Vehicles
The term safe state paints a picture of being secure, sheltered and guarded in one’s mind. To someone else it might be be associated with low-risk. Thus, the term safe state is a relative concept and debatable, and necessary guidelines have to be framed. The ISO26262 standard said that an arrangement or operating mode of a…

Implementable Ethics for Autonomous Vehicles
Autonomous vehicles constantly interact with other road users which include pedestrians, bicyclists, and human or automated drivers. These inter actions are governed by programmes and the order of importance given to the programmes by the programmers. The vehicle, just like any human driver, comes across a wide range of scenarios. From day to day common…

Introduction of Autonomous Cars
Introduction Autonomous driving has recently garnered the attention of the media due to declaration of success by car makers, system partners and companies. Autonomous driving is synonymous with a concept from science fiction in many minds. Defining the term autonomous driving may help in establishing a more realistic picture of the developments that have to…

Types of Vehicles
Motorcycles Companies such as Zero Motorcycles and Vectrix have market-ready all-electric motorcycles available now, but the pairing of electrical components and an internal combustion engine (ICE) has made packaging cumbersome, especially for niche brands. Automobiles and Light Trucks Microhybrids is a type of small hybrid electric car. Diesel-electric hybrid vehicles may soon see mass-production. Taxis Buses…

Production of Hybrid Electric Vehicles
Automotive hybrid technology became successful in the 1990s when the Honda Insight and Toyota Prius became available. These vehicles have a direct linkage from the ICE to the driven wheels, so the engine can provide acceleration power.
