Industrial Engineering
Industrial Engineering is the branch of engineering that deals with the creation and management of systems that integrate people and materials and energy in productive ways. An industrial engineer studies industrial productivity and makes and implements recommended changes.

What is the function of a relief valve and what is the disadvantage of it?
A relief valve is spring loaded valve that when excessive hydraulic or air pressure is applied it pushes the cylinder in the direction of the spring and lets the oil or air pass through and escape via another hose returning to the hydraulic tank or into the atmosphere in the case of air pressure. Without it hydraulic pipes or cylinders would rupture.
How did using interchangeable parts change the makeup of the labor force in the early 1800s?
Mostly known for their impact on the gunmaking industry, it allowed for a largely unskilled labor force to assemble products much faster and at a lower cost than before and in case of damage, made repair and replacement of parts endlessly easier.
What three types of constraints can be applied to CAD sketchs or models?
Geometric Constraint, Parametric Constraint, and Assembly Constraint
A hydraulic or hydrostatic drive system or hydraulic power transmission is a drive or transmission system that uses hydraulic fluid under pressure to drive machinery. The term hydrostatic refers to the transfer of energy from flow and pressure, not from the kinetic energy of the flow. Such a system basically consists of three parts. The generator (e.g. a hydraulic pump, driven by an electric motor, a combustion engine or a windmill); valves, filters, piping etc. (to guide and control the system); the motor (e.g. a hydraulic motor or hydraulic cylinder) to drive the machinery.
What grade of sandpaper is best for patching a hole in drywall?
You will get a better result using drywall mesh cloth, 2 grades about 120 and 180.
What are object lines used to identify?
Different thickness of lines denotes different things. Object lines are a specifice thickness (in relation to other lines on the same drawing) to visually identify 'objects'. Dimension lines are usually thinner, so as not to get confused with the lines that identify the object in question.
What things are made using investment casting?
I don't know what investment casting means if you don't know what it means ask your technology teacher insted
What is capacity consideration?
Forecast demand accurately
Understand the technology and capacity increments
Find the optimum operating level (volume)
Build for change
Who invented the corner tube boiler?
November 12, 1944, the first basic patent for Corner Tube Boilers (= Eckrohrkessel, Berlin, Germany) was applied for. During this time oil as fuel ran short. All efforts, to save energy and use domestic and alternate resources, were to be made. One came up with an idea, to operate cars and trucks, not on gasoline or diesel fuel, but with steam.
Dr. Vorkauf, a specialist for water circulation in boilers, especially in La Mont boilers (forced circulation boilers), got the order to design a small boiler for a steam engine fired with coal or wood. The result was not as expected a forced circulation boiler, but a natural circulation boiler. A forced circulation boiler of this size would have been too costly.
Due to his experience with the La Mont boiler Dr. Vorkauf had the idea to obtain a pre-separation of the steam - water mixture in front of the drum. An extremely lively water circulation resulted from unheated downcomers and a suitable arrangement of the mixture tubes. The unheated downcomers were installed in the 4 corners of the boiler, where they not only served the purpose of water circulation, but also as a support frame for the boiler. The boiler with such an arrangement of the downcomers in the corners was called Corner Tube Boiler (Eckrohrkessel, Eckrohr-Boiler).
Give 3 examples of pneumatic systems?
Pneumatic systems are usually closed systems. Blowing up a party balloon would be one example. A cycle pump would be another, and an air-based system for moving components in pipes would be another.
A windmill or a hand fan would not usually be considered to be pneumatic systems because they do not enclose the air component.
How do you destroy a Pillar drill?
drop either..........
A lump of concrete on it
A piano on it
Another Pillar drill on it
actually forget the piano!!!!!!!!!!!!!!!!!!
What is a role a person plays when in the feedback loop of a machine?
In any feed back control system, the controlling device has some parameters to be set (by the operator or person) before it is put to use, so that the system works under stable conditions. Also if the behaviour of the media (which is to be controlled) changes drastically the system may not work stable, which then needs a person's intervention.
What is Off-line robot programming?
Off-line Programming (OLP) is a Robot programming method where the Robot Program is created independent from the actual robot cell. The robot program is then uploaded to the real robot for execution. In off line programming the robot cell is commonly represented as a graphical 3Dmodel.
What is the difference between lining and coatings?
Linings are materials used to protect a container from corrosion and/or to protect the contents of a container from contamination by the container shell material. They are commonly thick, built-up systems that may or may not contain matting or similar reinforcing material.
Coatings generally refer to materials used for protective and/or functional purposes, while paints refer to materials used for aesthetics or decorative purposes. When coatings are used singly or in combination with reinforcing materials like matting, etc., they are termed as "lining", like for lining the inside of drinking water tanks.
However, there exist many similarities in composition, handling, and the use of paints, coatings and linings. There are also some differences.

It is a cost that is calculated based on how much the goods should returned profit for you If they were sold or rented to other company . This cost is important in the inventory holding cost Since by this cost you will judge either you produce the products and keep them or waiting until the order comes to you and produce only the desired amounts without keeping any amount in the inventory .
What is the shortage cost in inventory planning?
The penalty cost is the cost per unit of not satisfying the order when it is received. Shortage cost or stock-out cost is the total of all costs associated with shortage units. We use penalty cost in inventory planning. The penalty cost should not be something you pay actually. It can be like a chance of profit you missed, which is called the opportunity cost. However, there is a case when you should pay a penalty for the shortage. This happens when you have an agreement with a customer to satisfy the demand by a certain date with the right quantities, or you will pay a penalty for the breach of contract.
