Circular Saw- As changes in the economics of the industry occurred‚ developments in powered machinery began that had an impact on both preparing and assembling. In 1805‚ Brunel took out a patent for large circular saws particularly associated with veneer cuttingand in 1807 developed the saw further in association with block-making machinery. However‚ one of the most important developments was not on this scale at all. The small circular saw of up to seven inches diameter‚ often operated by a treadle

let´s go”. It was very cold out side Justin´s house. We took the bus‚ to the other side of the city. Justin and I live out side the city‚ so every Halloween we have to take the bus to the city. When the bus stopped‚ we went to the nearest house. I saw many pumpkins out side the houses. There were also small lights‚ inside the pumpkins. “ Ring‚ Ring”. An old man opened the door. “ Hello kids‚ what can I do for you?” “Trick Or Treat?” “ Oh sorry‚ I forgot it was Halloween today. I just go inside to

Dewalt reciprocating saw is a fantastic tool that helps your construction and demolition work accessible. There is no need to describe the application of a handheld tearing machine. In this article‚ we will study about different types of Dewalt reciprocating saws and the interesting facts that enhance the activity of these powerful machines. WHAT IS A RECIPROCATING SAW? A reciprocating saw is a tool used to cut metals and woods. The term reciprocal refers to the up and down motion of the cutting

1) Rivalry is a key force in the chain saw industry. There are a large number of firms already in the industry like Stihl‚ Huquvana‚ etc and this coupled with low industry growth‚ every company is vying for a larger share of the pie. High fixed costs also contribute to companies operating at near capacity and with high production‚ improving market share becomes critical. Also high exit barriers in this industry negate the ease of abandoning the product‚ thereby increasing rivalry.

Circular Motion Uniform circular motion is the movement of an object or particle trajectory at a constant speed around a circle with a fixed radius. The fixed radius‚ r‚ is the position of an object in uniform or circular motion relative to to the center of the circle. The length of the position vector of the circle does not change but its direction does as the object follows its circular path. In order to find the object’s velocity‚ one needs to find its displacement vector over the specific

Among the high-quality power tools offered by DeWalt are table saw‚ drills‚ and miter saws. Miter saw is one of the most important power tools used in woodworking. It is designed to provide accurate miter and crosscuts on different types of woods. There are several factors that should be considered when buying a miter saw including the size and materials that will be cut‚ the cutting capacity of the miter saw‚ and its capabilities. Miter saws are available in different sizes and configurations with different

Uniform Circular Motion – a constant motion along a circle; the unfirom motion of a body along a circle Frequency (f) – the number of cycles or revolutions completed by the same object in a given time; may be expressed as per second‚ per minute‚ per hour‚ per year‚ etc.; standard unit is revolutions per second (rev/s) Period (T) – the time it takes for an object to make one complete revolution; may be expressed in seconds‚ minutes‚ hours‚ years‚ etc.; standard unit is seconds per revolution

Circular Motion and Gravitation Circular motion is everywhere‚ from atoms to galaxies‚ from flagella to Ferris wheels. Two terms are frequently used to describe such motion. In general‚ we say that an object rotates when the axis of rotation lies within the body‚ and that it revolves when the axis is outside it. Thus‚ the Earth rotates on its axis and revolves about the Sun. When a body rotates on its axis‚ all the particles of the body revolve – that is‚ they move in circular paths about

Title: Uniform Circular Motion Objective: To investigate the relationship between FnetT² and radius Proposed Hypothesis: FnetT² is directly proportional to the radius Manipulated variable: Radius of the circular motion Responding variable: The time taken for 20 rotations Controlled variables: The mass of the rubber stopper‚ the mass of the weight hanger‚ the total weight of the slotted weight‚ the length of the PVC tube Apparatus and Materials: rubber stopper‚ stopwatch‚ weight

II Uniform Circular Motion A. Nomenclature 1. Speed – magnitude of an objects rate of motion (no direction‚ scalar quantity) 2. Velocity – speed and direction of an objects motion (vector‚ mag & direction) 3. If a car’s speed is constant but direction is changing‚ velocity is changing. 4. 2 ways to change velocity (change speed or change direction). 5. acceleration – change in speed over time (vector quantity) TWO types; a. Linear acceleration – speed
