A bow is basically a two-armed spring that stores mechanical “potential energy” once the string is drawn and pulls back the limbs. After you recoil the cord, you utilize your muscles to exert a force on the string that bends the limbs backward. The quantity of force that your fingers exert on the string once you’ve to force it all the means back is named the “draw weight.” The elastic or spring energy is currently “potential energy” that may be reborn into launching associate arrow after you…

Intuitively we know that the size of an object can have a significant impact on its dynamics. We have seen athletes or animals creating moves beyond our imagination, as shown in Fig. 4.1. This is because their ability in manipulating different parts of their bodies in creating dynamic complexities shown in the images. Certainly we would not be able to ignore the role played by each part of the body if we were to analyze the dynamics of an extended object. However, there is one point, associated…

1. C Why: according to Newton’s first law of motion, an object that is free from all outside forces travels at a constant velocity, covering equal distances in equal times along a straight-line path, C is true. 2. D Why: not matter an object is still or is in motion, the object has inertia all the time. Inertia is a nature/property of any objects. 3. D Why: the ship is moving at a constant speed, which is in a balanced status. For the athlete, it would be likely to do a long jump on ground.…

CHAPTER 5 EXPERIMENTATION 5.1 Spur gear terms and concept Fig. 5.1 Terminology definitions for spur gears The radial distance from the pitch circle to the outside diameter is called as addendum. The radial distance between the pitch circle and the root diameter is called as dedendum. The distance of the arc along the pitch circle from one side of a gear tooth to the other is called as circular thickness. The length of the arc of the pitch circle from one point on a tooth to the same…

Particle Deformation and Fragmentation: As compaction force increases, contact area between particles increases, particle deformation starts to occur. Elastic deformation: granules attempt to return to their original shape or form after stress is released. Plastic deformation: granules do not totally recover after stress is released. Fragmentation occurs when compaction force continues to increase Particles fracture, create multiple new surface sites, additional contact points and potential…

1. Derive the mathematical expression for the Lorentz transformation equation. relative orientation of the co-ordinate systems indicated in fig.2 A light-signal, which is proceeding along the positive axis of x, is transmitted according to the equation : x - ct = 0 _______ (1). Since the same light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula x' - ct' = 0 _______(2) therefore:…

The differences between barefoot and shod running Introduction: Humans have the ability to perform various movements, such as jumping, walking, running, etc. However, tend not to think the essentials of movement as they are not applying the mechanisms that allow them to move from one place to another. The amount of energy required to walk at a comfortable place is very small in comparison with other activities (Everett and Kell, 2010). The study of De Wit et al, (2000) concluded that,…

Introduction: The purpose of this lab is to help students gain a better understanding of physical concepts such as work (which occurs when an applied force moves an object.) torque (defined as a twisting force), energy and rotational inertia (an object's resistance to rotation). Experimental Design: My group’s testable question throughout the mousetrap car experiment was: If we add and subtract factors such as material, weight and shape, from the wheels of our car, how will it affect the…
