Why they are letters and numbers printed in the border of engineering drawings?
There used to specify zones on the drawing. Similiar to map ordinates to define a location. i.e. The feature is shown in C6 They can also be used during revision control to highlight areas of change with balloons or tags. i.e. B7 Feature remove or E2 Dimension was 365

What is idealization of mechanics in Engineering mechanics?
A number of ideal conditions are assumed to exist while applying the laws of mechanics of practical problems. in fact, without such assumptions, it is not feasible to arrive at practical solutions. The experience in the past centuries has shown that the following idealization could be made as they do not bring down the accuracy of the analytical results below the optimum level required by engineers to deal with practical diagram.ContinuumA body consists of several particles. It is a well known fact that each particle can be sub-divided into molecules, atoms and electrons. It is not feasible to solve any engineering problem by treating a body as a conglomeration of such discrete particles. The body is assumed to consist of a continuous distribution of matter which will not separate even when various forces considered are acting simultaneously. In other words, we say the body is treated as a continuum.Rigid BodyAs already stated, in Civil Engineering, we treat a body as rigid, when the relative position of any two particles in the body do not change even after the application of a system of forces. For examples, let the body shown in figure (a) move to a position as shown in figure (b) when the system of forces F2 and F3 are applied. If the body is treated as a rigid body, the relative position of A to B is the same as A' and B', i.e.,AB = A'B'ParticleA particle may be defined as an object which has only mass and no size. Theoretically, such a body cannot exist; while dealing with the problems involving distances which are considerably larger compared to the size of the body, the size of the body may be neglected without sacrificing the accuracy, the example are as follows:A bomber aeroplane is a particle for a gunner operating from the ground.A ship in a mid sea is a particle in the study of relative motion from the control in a part.In the study of the movement of earth in celestial space, earth is treated as a particle.
What is battery limit in piping design engineering?
Unit plot plans are generally defined by imaginary lines called battery limits. Battery limits are used to establish a unit's boundaries. Unit plot plans show the location of all the buildings, equipment, pipe racks, and other items of importance in the unit. True north and plant north are also shown. The purpose of this drawing is not to show detail, but rather, the arrangement of various components to be erected in the unit.
What is bourdon tube pressure gauge?
An elastic transducer, that is bourdon tube which is fixed and open at one end to receive the pressure which is to be measured. The other end of the bourdon tube is free and closed. The cross-section of the bourdon tube is eliptical. The bourdon tube is in a bent form to look like a circular arc. To the free end of the bourdon tube is attached an adjustable link, which is inturn connected to a sector and pinion as shown in diagram. To the shaft of the pinion is connected a pointer which sweeps over a pressure calibrated scale.

What is an advantage of polyconic projection?
· isometric drawings disadvantages· It can be difficult to get a clear picture of how the different views fit together to form the final part.· Not all views shown i.e. the base· Dimensions not always shown· Hidden detail not always shownOrthographic drawings advantages· It gives you all dimensions· All hidden detail are shown· It gives you view from all the sides.
What is the definition for dual dimensions?
Dual dimensions in engineering is when both the English system's unit for the dimension and the metric system's unit for the dimension are shown together as two stacked dimensions.
On a manufacturing drawing what does it mean to hold dimension?
Every dimension has a shown or implied tolerance, the dimensions shown as HOLD are the dimensions that are not to be affected by the stack up of tolerances of the holes or features around them.
How are drawings animated?
A series of drawings, with each only slightly different than the one before it, can be shown in rapid succession, which creates an illusion of motion.

As there is no system of equations shown, there are zero solutions.
What is the difference between a phycical map and a potenial map?
The difference is that a physical map is shown by the drawings of features while the potential maps will have descriptions of the place.
Does drawings go onto the income statement?
Drawings is a contra account to owner’s capital which is used for owners withdrawals from business so it is not part of income statement rather it is part of balance sheet and shown as a deduction from owner’s capital.
