Why is it important to use a fixed common reference point for dimensioning of drawings and sketches?
It is important to use a fixed common reference point on your work peace or drawing to avoid cumulative error, i.e. if a hole is drilled using an incorrect measurement initially, then continuation to measure from the error instead of using a common reference point could result in a whole piece of work being scrapped. Also if somebody has to take over the work, they would need to understand were the dimensions were taken from to enable them to carry on with the work.
Why is the moment of a couple a free vector?
A couple is a mechanical term defined as a system of forces that produces a resultant moment but not a resultant force. The moment caused by a couple is different than the moment caused by a single force. The moment of a force is dependent upon a reference point (i.e. if this reference point changes the moment also changes), therefore it is a fixed (or bound) vector. However, the moment (or torque) of a couple is independent of a reference point. In other words any reference point will give the same torque. This fact is proven in Varignon's Second Moment Thereom. Since the moment (or torque) of a couple is independent of a reference point, it may be represented as a free vector. This means that the vector may be freely moved in space.
What is the function of the lever?
A lever can rotate around the fixed point that is called a pivot. Levers are used to reduce the force need to do a particular task.
What is compressor turndown?
Turndown: The allowable operating range for the centrifugal compressor between the design point and the surge line at any given speed for a fixed compressor head.
The simple machine that provides a mechanical advantage of one?
Single fixed pulley
What is the fix reference point in photos?
What is the fixed reference point in the photos?
How important the point reference?
Without a fixed Point of Reference, there is nothing to be relative to.
What does reference point mean when having to do with speed?
A reference point in the context of speed is a fixed location from which the speed of an object is observed or measured. It provides a frame of reference for determining the speed of an object relative to that fixed point.
What is a fixed place on the earths surface?
reference point
What is a common frame of reference when you describe motion?
A common frame of reference when describing motion is the observer's point of view or a fixed point in the environment that is used as a reference to describe the motion of an object. This helps to establish direction, speed, and location of the object in relation to the observer or the fixed reference point.
Why do we always start at the origin point?
It is because many things are measured with reference to a fixed point: it space or time. This point is called a reference point or origin.
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 is the symbol for the reference point?
The symbol for the reference point is usually denoted as "O" in geometry and physics. It is used as a fixed point from which position, distance, and direction are measured.
What is movement with respect to a reference point?
Movement with respect to a reference point refers to the change in position of an object relative to that reference point. It can be described in terms of distance covered and direction traveled. The reference point serves as a fixed point from which the movement of the object is measured.
Fixed reference point?
A frame of reference in physics, may refer to a coordinate system or set of axes
What is the upper fixed point in the thermometer?
The upper fixed point on a thermometer is the temperature set at 100 degrees Celsius, which corresponds to the boiling point of water at standard atmospheric pressure. This fixed point is used as a reference point for calibrating the thermometer.
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.
