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…

Electric current is measured in amperes (A). Voltage: The difference in electric potential energy of charged particles between two points within the electric field is called voltage. The free electrons at the higher potential have more electrical potential energy whereas the free electrons at lower potential have less electrical potential energy. Voltage is measured in volts (V). Resistance: Resistance is the…

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…

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…

Model Scenario During recess on a sunny August afternoon, I noticed several of my students gathered together on the sidewalk. I walked over to see what the fascination was about, and found that one of the students had several types of magnets and other materials. The students appeared to be genuinely interested in discovering what would and would not attract to the different types of magnets. Once we returned to the classroom, several students made statements about characteristics and…

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…

Library Research The concept behind torsion spring powered alternative energy vehicles can be understood through a widely used high school physics experiment—the mousetrap car model (Roberts & Gonzalez-Espada, 2006, p. 15). The mousetrap model is very straightforward (Jumper, 2012, p. 137). A bow with a lever arm is installed in the model car, and this lever arm is then connected to the car’s rear axle with string. At rest, when potential energy is at its lowest, the lever arm is leaning…
