A skid steer loader is a versatile machine, and a must have for anyone in landscaping, large-scale construction, farming, or logging. It has a rigid frame and lift arms you can attach various tools and skid steer loader attachments to. Loaders may be track-equipped or four-wheel drive. The drive system of the loader has no transmission. Instead, it uses pumps and hydraulic motors to power the wheels or tracks. Wheels can drive independently of each other, which makes them very maneuverable.…

Callaway Steelhead XR Irons: There are motor-heads. There are rock-heads. And then, there is steelhead. Steelhead XR irons are the latest offering from Callaway. Allow starting the section by qualifying the aforementioned statement. The steelheads irons are the foremost flagship offering of the Callaway. Golf aficionados’ would agree that golfing, steelhead and Callaway are almost synonymous. In the past, Callaway offered many series in the flagship starting from X-14 through X-22. However, the…

1.1 Dielectric Materials Dielectric materials are insulating materials that exhibit the property of electrical polarization. Dielectric materials support charge by acquiring a polarisation in an electric field. 1.1.1 Electric susceptibility and permittivity When a capacitor with capacitance C0 is filled with a dielectric material, its charge storage capacity (capacitance) increases to a value of C. Than susceptibility (χ^') of the dielectric materials is given by χ^'= (C-C_0)/C Dielectric…

I. Purpose: The purpose of this lab is best understood by the principles of static electricity, as two rough objects rub against each other the atoms of those objects touch and pull upon each other sporadically. When this occurs the electrons of those atoms will transfer between these objects and static electricity is generated. This lab is performed to see the role that static electricity has on objects, when determining their charge and how they interact, all seen by a firsthand course of…

I. INTRODUCTION HE versatility of muscles is a crucial factor for efficient animal locomotion. In combination with a high degree of force control muscles enable precise motions depending on the wanted action. Animal locomotion involves (a) fine motor skills like sneaking, grabbing and communication; (b) quick short term acceleration like catching prey; (c) very long-term movement patterns which need to be performed efficient like digesting, migration and sometimes even (d) avoiding motion by…

What chracterizes the axial flow turbine is its rotation axis. It could be placed vertically or horizontally to water surface. In this latter type the axis is parallel positioned to the incoming water stream. Also the generator can be submerged under water or non-submerged. This turbine is usually used as tidal energy converter. For small river use, the axis could be an angle inclined to the water stream. See figure \ref{Hydro_HorizontalAxis}. Hydrokinetic converters with a vertical axis…

Wheatstone bridge is a device used to measure unknown resistance by passing current through the resistor [1]. Wheatstone bridge is made up of a power source and galvanometer that joins the two-parallel circuits which contains two resistors each. It is very useful in finding small resistances and is used in various applications such as strain gages. The following figure shows the arrangement of a Wheatstone bridge. Figure 1: Arrangement of a Wheatstone Bridge [1] Importance of Wheatstone…

Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…
