You would either need a 4 jaw chuck or a faceplate.

I would use a wire feed MIG, or a oxy-fuel torch. If arc welding, use a low power. It's really easy to burn through exhaust pipes and mufflers.

Maybe, maybe not. It all depends on how the assembly is designed. You don't have to use them, but you don't have to avoid them either.

It takes a longer time to drill a hole than it should. You see burning or smoking instead of chips.

A CNC system consists of three basic components :

1 . Part program

2 . Machine Control Unit (MCU)

3 . Machine tool (lathe, drill press, milling machine etc)

The principle of lift is well-illustrated by the motion it causes.

Density has more to do with the the carbon levels in the steel, grading the steel based on the make up determines cost price and use. Steel nails are often made from the worsed parts or slag from bigger batches, due to this, making them less dense by compairison. The range of raw materials by witch steel is made is quite astronomical with well over a thousand types of aluminium. as an example.

An Engineering Portfolio is a website or document that highlights examples of your work and projects. ... Portfolios increases one's awareness of their skills and abilities; it is another way to connect in-and-out of classroom learning with real world applications. Show off your work, your projects, and your passions

What defines a shape as being aerodynamic is that is has as little resistance as possible at the front of the shape (whichever direction is moving forward) and also allows the air to rejoin after the shape with as little turbulence as possible. So the most aerodynamic shape would be a needle that is pointed at both ends. However this shape is not really useful in most applications, but the idea of this pointed at both ends shape can be seen in many of the newer cars. Look at a prius for example, the front is pointy and the back is designed as a point but is cutoff prematurely.

Calculate the volume of the outer cylinder as pi*r*r*h where pi = 3.14159, r = 195, and h = 3400. Calculate the volume of the inner cylinder with r = (195 -25) = 170. The difference between the two is the volume of MS (steel used). density = mass / volume mass = density * volume. weight = mass * gravity (= 9.8)

I changed the brakes on a 1997 Holden Barina SB today (21/5/11). You will need a 10mm Allen key to take off the brake housing. Do yourself a favour and buy a set of Allen key type attachments for a ratchet. Makes it much easier.

Depends on a lot of variables, such as welding process, filler metal, type of joint, etc. One possibility is that a proper pre-heat is not maintained. If welding two thick pieces of plate, by the time the final passes are welded, the bottom layers may cool too quickly, or the beads may not be fusing together. Cooling too quickly can cause the layers to separate. Or it may be possible that the continuous welding with a certain process may overheat the metal. Also, some electrodes contain hydrogen that can cause embrittlement and cracking in the parent metal or HAZ. This list is not exhaustive, consult a welding text for more potential causes.

In reality if the proper motor protection is used, no motor should burn. Even a motor that has a locked rotor will trip the heater overload protection. So the issues to be looked at that would cause a motor to burn would be, is the motor protection correctly sized? The motor must be running within the manufactures specifications and not outside the motors service factor. The supply breaker and wiring to the motor must be the correct size. The overload protection should be in mid scale of the settings. House keeping around motors is a big condition to keep a motor running within its parameters. Cooling fins and fans must be kept clean of any debris. All of this should allow a motor to run free of trouble for many years.

The computer, the pen are manufactured through controlled engineering processes. The transport and communication that we use everyday requires materials engineering.

PICAXE is a fairly good system. The programming language is not the most efficient, but it will allow you to put quite interesting things together quickly and start experimenting, without wasting time on selection of components, etc.

you actually answered your own question, there are many different speed control devices for pneumatics,since there so many applications finding the correct device may take some research. make sure that the device is suitable for the high pressure side of the system,basically a speed control device is a throttling valve

Bronze is an alloy of copper and tin. It may also contain phosphorus, manganese, aluminum, or silicon.

It is not of fixed ratios.

Ceramics are inorganic, non metallic materials formed using heat. Examples include bricks, clay pots, porcelain, titanium carbide, silicon carbide, ect. If you googled 'examples of ceramics' you would be sure to find many examples.

momentum is product of moment of inertia and angular velocity. There is always a 90 degree phase difference between velocity and acceleration vector in circular motion therefore angular momentum and acceleration can never be parallel

I am a senior student in mechanical engineering I ve been looking for this answer for a long long time but i cannot even find a degree specialized in stress analysis

So i guess that in order to become a stress analyst, you need to master:

Mechanical Design

Mechanics

Strength of Materials

Mechanics of Solid

Also I suggest that you start using some mechanical design and stress analysis programs in order to be fully fonctional when you ll apply for a job

CATIA/PRoE

NASTRAN/ANSYS

I ve been doing it with CATIA and ANSYS

Of course i did not purchase the licence if you know what i mean (internet is a goldmine) ...

Take care.
