What is the function of universal dividing head in a milling machine?
The function of the dividing or indexing head is to equally space the required amount of grooves to be cut into a component. An example would be a gear or a shaft with a spline at the end. It can also be used for high precision drilling of holes. cutting hexagons or other shapes, etc. With the right attachments a dividing head can be connected to a universal milling machine's table screw, enabling it to rotate as the table moves along its sideways axis. This is useful for helical grooving of which a drill bit or helical gear are examples.
An almost similar device to a dividing head is a rotary table.
Logarithms were originally used to convert multiplications into additions and divisions into subtractions (plus some looking up in tables).
To multiply 3456 by 6789
- Look up in table: log(3456) = 3.5386
- Look up in table: log(6789) = 3.8318
- add them together = 7.3704
- Look up in table: antilog(7.3704) = 107.3704 = 23460000
So the only calculation is a simple addition at step 3.
Logarithms were often used for approximate calculations (4 significant figures), but there were tables for more accurate work.
Nowadays, though, it is easier to use calculators for multiplication and division.
There is a whole class of problems where the solution involves logarithms. If the rate of change in a variable X is directly proportional to the quantity X, then the solution involves logarithms (or its inverse, exponents). Typical textbook examples include radioactive decay, simple chemical reactions, bacterial {or any uncontrolled] growth, compound interest.
Which is higher profession mechanical engineer or architect?
Architect is higher Profession as compare to Mechanical Engineer.
What is the formula for energy consumption?
Wattage X hours used per day X number of days used ÷ 1000
What is vfd called as variable frequncy drive?
VDF is variable frequency drive.
In AC (alternative current) induction motors the speed is obtained by parameters like poles and frequency
formula Ns = 120 x f/ p
where N= (synchronous ) speed rpm of motor. F = frequncy Hz of the power supply ex:50Hz, 60 Hz
to obtain variable speed of the motor by changing the frequncy it is achived with the help of VFD device.
How do you calculate LAP length of steel reinforcement bar?
one trapozoidal section of 0.5 sloping distance is one side and 0.5 is the another side and 1.0 meter is the horizontal base . what will be the cutting length for it.
Difference between Diffusion and ion implantation?
diffusion is high temperature process while ion implantation is low temperature process
What is the hardness of sodalite?
Siltstones do not have a Mohs hardness. Relatively speaking, however, siltstones are relatively easily broken.
What is the great belt bridge made of?
Two bridges make up the Great Belt fixed link:
- the East Bridge (Halsskov - Sprogø) is a road suspension bridge;
- the West Bridge (Sprogø - Knudshoved) is a box girder road and rail bridge.
This is known as the Modulus of Elastisity, or Youngs Modulus (in tension/compression) and will be a constant as long as the deformation is in the elastic range.
What are the examples of mini computer?
A computer that is designed small and used to fit and save desk space when space is needed. Some get really small and can attach to the back of an lcd monitor and run off batteries. They have smaller components, smaller cases, smaller power supplies, smaller power usage as well.
What is traditional file processing system?
The traditional file processing system is the computerized manual filing system. It is when a computer system stores permanent records.
How much pressure can a full soda can withstand?
Conducted a lab at school measuring the strain on a soda can when it was opened. Back solving for the force as if the can were a thin walled pressure vessel led us to P = -54.447 +- 0.047288 Psi to 95% confidence.
When objects are cooled down, they contract. Engineers who put up telephone wires in the summer leave the wires hanging slack so that in winter, the wires have a chance to contract without pulling the poles and damaging property or infrastructure.
For ss welding which electrodes should be used?
This would depend on several variable such as: Welding process being used (SMAW, GMAW, etc). Specific type and grade of the Stainless Steel. The required tensile strength, ductility, and corrosion resistance. If you are welding pressure piping, the applicable ASME codes have a table in section IX. AWS D1.6 addresses structural applications. There are three basic types of Stainless Steels. Austenitic, Martensitic, and ferritic. Each has characteristics that differ from each other in the post welded condition. For a good selection of electrodes and their applications, your local welding supplier should have free reference books by various suppliers that will help. These are the same books we us to assist us in developing welding procedures to various codes and standards.
What happens to mild steel ships hulls operated in freezing waters?
Somebody is doing a Btec.
Go do some research like the rest of us mugs.
Is biomedical engineering lucrative?
The field of biomedical engineering is diverse and can launch you into many different paths. Biomedical engineering as a discipline can line you up for a job in many enginering firms, in medicine, and especially in research. Graduates can go on to earn masters or PhD degrees in specialties that allow them to design medical devices, human-computer interfaces, and data analysis tools that help people every day.
In short, if you work hard, you can find a place for yourself and expect to earn 50,000 starting salary and up with experience and degree level.
What is the unit weight of 150 mm diameter GI pipe?
3.04kg/mtr for 32mm(M) also used as riser pipes for Hand Pump Mark-II
- bipolar devices use both majority and minority current carriers
- unipolar devices use only majority current carriers
How do you convert MBH to Tons?
MBH stands for "thousands of BTUs per hour.". There are 12,000 BTUh per ton, so there are 12 MBH per ton. So, to find tons, divide by 12.
