What is the difference between a general engineering contractor and a general building contractor?
A general engineering contractor is a contractor whose principal contracting business is in connection with fixed works requiring specialized engineering knowledge and skill, including irrigation, drainage, water power, water supply, flood control, inland waterways, harbors, docks and wharves, shipyards, roadways, airports, bridges, etc. A general building contractor simply builds buildings.
Is 46-16 a good gear ratio for a fixed gear?
Yea
What is a hanging object with a fixed point that swings freely back and forth?
pendulum
What simple machine is used in venetian blinds?
The blinds use a pulley (fixed pulley).
What is LATA an acronym for in technology?
The meaning of the acronym LATA within the US telecommunications sector is "local access and transport area". These areas are not fixed by state boundaries.
Fixed reference point?
A frame of reference in physics, may refer to a coordinate system or set of axes
Where is the fixed point in the universe?
There do not appear to be ANY "fixed points" in the Universe. Everything is in motion, and there is no "preferred" frame of reference.
Why it is important to use a fixed common reference point for dimensioning of drawings and sketcher?
Using a fixed common reference point for dimensioning in drawings and sketches is crucial for ensuring consistency and clarity. It helps in accurately communicating dimensions and relationships between different features, making it easier for designers, engineers, and manufacturers to interpret the drawings. This common reference minimizes errors and confusion, facilitating better collaboration and reducing the likelihood of costly mistakes during the production process. Overall, it enhances the overall precision and quality of the design work.
Why is it important to used fixed common reference point for dimensioning of drawings and sketches?
Using a fixed common reference point ensures consistency and accuracy in dimensioning, making it easier for multiple people to interpret the dimensions on a drawing or sketch. It eliminates confusion and errors that can arise when referencing dimensions from different starting points, resulting in more precise and reliable measurements.
How do we use reference points to determine whether motion has occurred?
Reference points are used to determine motion by comparing the position of an object relative to those points over time. If the object changes its position relative to the reference points, then motion has occurred. By observing the changes in the object's position relative to fixed points, we can determine its motion, speed, and direction.
What does 'fixed in space' mean?
"Fixed in space" means that an object's position or orientation remains constant relative to a reference point or frame of reference. This term is often used in physics and engineering to describe an object's stability or lack of movement in a specific spatial context.
Explain why reference points that are stationary are usually chosen to determine whether an object is in motion?
Stationary reference points are chosen to determine motion because they provide a consistent and fixed frame of reference. By using stationary reference points, it is easier to identify when an object is moving relative to its surroundings. This helps in accurately measuring the speed and direction of the object's motion.
Why is the origin important when graphing points on the coordinate plane?
It is because all measurements are taken from that point: it is the fixed point of reference.
What is a fixed point use to determine movement?
A fixed point is a reference point that remains constant during movement, allowing us to determine the direction and distance of the movement relative to that point. By using fixed points as landmarks or reference markers, we can navigate and track the changes in position accurately.
What three examples of reference points that are stationary relative to earth?
Three examples of reference points that are stationary relative to Earth include the North Star (Polaris), which provides a fixed point in the sky for navigation; the geographic poles (North and South Poles), which are fixed locations on the Earth's surface; and a specific point on the Earth's surface, such as a landmark or building, which remains in the same location over time. These reference points help in measuring movement and position relative to the Earth.
What is the imperial and metric systems of measurement tolerancing and fixed reference points?
The imperial system of measurement, primarily used in the United States, relies on units such as inches, feet, and pounds, while the metric system, used globally, is based on units like meters, liters, and grams. Tolerancing in both systems defines the allowable variations in dimensions, ensuring parts fit and function properly. Fixed reference points, such as datum features in engineering, provide a consistent basis for measurement and alignment in both systems, facilitating accurate manufacturing and assembly processes. Each system has its own conventions for specifying tolerances and reference points, tailored to the needs of their respective industries.
Is a fixed location in space?
A fixed location in space is a point in the three-dimensional coordinate system that remains constant and does not change its position relative to other points. It serves as a reference or anchor point for measuring distances and positions within a specific frame of reference.
