Create Auto save macro in Excel?
In XLS 2003 you can simply turn the "Save AutoRecovery info" in EXCEL (Tools/Options/Save)
How is sectional line should be drawn?
when any object like hollow cylider, cut in to two halves or two pieces than its cutting section show by section line.
and the lines are at 45 degree and space is around 1.5 to 2mm between to lines.
What is the difference between SINR and CINR?
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
Make a bubble of liquid on top of a surface then either
Spin the chip on a spinner, or
Wait 30 seconds and rinse with clean solvent, or
Wait until on all solvent evaporates (this will leave drying spots, non-uniform coverage)
In chemistry, the dropcast method is commonly understood to be the latter (no. 3), pipetting a compound dissolved in solvent onto a surface and left to dry. As stated previously, non-uniform coverage and small volumes make repeatability an issue.
What are the uses of technical drafting?
Technical drafting is used to create detailed and precise representations of objects, structures, or systems in various fields such as engineering, architecture, and manufacturing. It serves as a communication tool, allowing designers and engineers to convey their ideas clearly and accurately. Drafting is essential for the production of blueprints, schematics, and plans, facilitating the construction and fabrication processes. Additionally, it aids in documenting specifications and revisions, ensuring consistency and quality in projects.
Although a lathe can bore and drill, it is actually associated with turning.
A drilling machine is associated with drilling, a milling machine with milling, and a boring mill with boring.
How does face milling differ from peripheral milling for producing flat surface?
In face milling:
a) The axis of the cutter rotation is perpendicular to surface being milled
b) The machining is performed by the cutting edges on both the end and outside
periphery of the cutter
In peripheral milling:
a) The axis of the cutter rotation is parallel to the surface being machined.
b) The operation is performed by the cutting edges of the outside periphery of
the cutter
Can resource allocation graph have cycles without a deadlock?
yes resource allocation graph have cycles without a deadlock existing.
What filler metal is used to weld 308 stainless steel?
dissimilar steel grades and the unknown grade ss can easily welded with the help of
680CGS lnt welding electrode
What is the advantage of size proportion in a model?
In fashion modeling it is all about the sample sizes used when fitting clothes onto a model. Having the right size proportions not only ensures the model will be able to successfully fit into the garments and wears the style the way the designer intended.
Why is CO2 unsuitable for electric fire?
You are wrong, CO2 is particularly used to extinguish electrical fires.
According to the EPA:
(...) some of the types of hazards and equipment that carbon dioxide systems protect are "flammable liquid materials; electrical hazards, such as transformers, switches, circuit breakers, rotating equipment, and electronic equipment (....)
and they also mention the reason:
Carbon dioxide is the most commonly used "inert" gas extinguishing agent, followed by nitrogen (Friedman 1992) (...) Carbon dioxide fire extinguishing systems are useful in protecting against fire hazards when an inert, electrically nonconductive, three-dimensional gas is essential or desirable and where clean up from the agent must be minimal (...)
1) Decide on a position for the vectors; for example, place one of them along the x-axis (from left to right).
2) Making a drawing is sort of optional, but it helps visualize the problem. This might save you from making mistakes.
3) Convert both vectors to rectangular coordinates. The polar-->rectangular conversion, available on most scientific calculators, can help a lot with this.
4) Add the x-coordinate and the y-coordinate of both vectors separately.
5) Convert to polar coordinates (once again, using the corresponding function on your scientific calculator). One of the numbers given, in polar coordinates, is the magnitude of the vector; the other is the angle.
What is the difference between Breaking Strength and Modulus of Rupture (ceramic tile)?
The modulus of rupture is the same as the breaking strength. It is a term used for ceramics where strength is dependent upon statistical distribution of flaw size, flaw shape, and moisture.
