First off you should know what a rock cycle is. The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary‚ metamorphic‚ and igneous. Rocks make rocks. The cycle begins within the core of the earth. The molten rock in the core of the earth is called magma. Once the rock is forced to the earth’s lithosphere or crust‚ the molten rock becomes lava and thereby begins its long journey of development

and a motor in a circuit with two jumpers. 4. The theory was applied. The jumpers were connected to the alternate voltage supply. 5. The direction of DC motor was tested and determined. 6. All switches were in closed position at initial condition. 7. Only switch 1 and 4 was closed at the first condition as in figure 2(a). The direction of DC motor and the RPM of DC motor was recorded 8. Switch 1 was opened and switch 2 was closed as in figure 2(b) after the first reading was recorded. The motor was

ELECTRIC MOTORS I. Introduction Electric motors are considered to be important mechanical devices. They usually convert the electrical energy coming from the mechanical device into its kinetic energy to make it work (Petingco and Resurreccion‚ 2011). In this exercise‚ the students were tasked to use an example of an electric motor‚ identify its parts‚ and make it work. All electrical motors are equipped with stator and rotor. Stator is known as the stationary part of an electric motor while

EPHE 380 – Motor Control Final Exam Ian Haig V00711512 Scenario: Walking down a 45 degree slope with a surfboard under my left arm and a large mountaineering backpack on my back. I was walking down the trail to Sombrio Beach which is about a 1.5k hike down a steep trail to the ocean. I had a surfboard under my right arm‚ an axe in my left hand‚ and a large 40 litre hiking backpack fully loaded with supplies on my back. About half way down there is a left turn in the trail which has a declining

READ MOREBrushless DC Motors are an important class of highly efficient electric motors. They are most frequently used in electric vehicles because of their high efficiency and high power density. They are also present in the small DC fans used in power supplies and CPU coolers. In order to discuss the Brushless DC Motor it is important to first have a basic understanding of the more common Brushed DC Motor which is present in many household items. The brushed DC motor consists of a rotor (the

Design of Induction Motors Introduction: Induction motors are the ac motors which are employed as the prime movers in most of the industries. Such motors are widely used in industrial applications from small workshops to large industries. These motors are employed in applications such as centrifugal pumps‚ conveyers‚ compressors crushers‚ and drilling machines etc. Constructional Details: Similar to DC machines an induction motor consists of a stationary member called stator and a rotating

Vehicle insurance Vehicle insurance (also known as auto insurance‚ GAP insurance‚ car insurance‚ or motor insurance) is insurance purchased for cars‚ trucks‚ motorcycles‚ and other road vehicles. Its primary use is to provide financial protection against physical damage and/or bodily injury resulting from traffic collisions and against liability that could also arise therefrom. The specific terms of vehicle insurance vary with legal regulations in each region. To a lesser degree vehicle insurance

Motor Graders in Construction The motor grader is a large multipurpose machine used for many different construction operations. These many operations include but are not limited to: grading‚ shaping‚ bank sloping‚ ditching‚ and scarifying. Graders can also be employed to clear roads of snow and debris without doing any damage to the underlying roadway surface. Graders are much more “gentle” than dozers and other large pushing machinery. Motor graders are designed for preparing the substrate of roads
