Linear:

(english) A structure is said to behave linearly when its the deformation response is directly proportional to the loading (i.e. doubling the load doubles the displacement response). For a material, linear means that the stress is directly proportional to the strain.

Revibration

(Concrete Engineering) Delayed vibration of concrete that has already been placed and consolidated. Most effective when done at the latest time a running vibrator will sink of its own weight into the concrete and make it plastic and workable again.

Pin support:

(english) In two dimensions, a pin support restrains two translation degrees of freedom but does not restrain rotation. When considering reaction forces, a pin support is usually considered to have two force components: one each about the x and y axes respectively.

rathole

When are you going to be able to move out of that rathole?

Mixing Speed

(Concrete Engineering) Rate of mixer drum rotation or that of the paddles in a pan, open-top, or trough type mixer, when mixing a batch; expressed in revolutions per minute (rpm) or in peripheral] feet per minute of A point on the circumference at maximum diameter.

Flexibility:

(english) Flexibility is the inverse of stiffness. When a force is applied to a structure, there is a displacement in the direction of the force; flexibility is the ratio of the displacement divided by the force. High flexibility means that a small load produces a large displacement.

Pressure:

(english) Pressure is a similar idea to stress, the force intensity at a point, except that pressure means something acting on the surface of an object rather than within the material of the object. When discussing the pressure within a fluid, the meaning is equivalent to stress.

blimp

I always seem to have a blimp sitting next to me when I travel.

There is a magnet in your heart that will attract true friends. That magnet is unselfishness, thinking of others first. When you learn to live for others, they will live for you

มีแม่เหล็กอยู่ในหัวใจของคุณ ซึ่งจะดึงดูดมิตรแท้ แม่เหล็กชนิดนี้คือ ความไม่เห็นแก่ตัว และการคิดถึงคนอื่นก่อน เมื่อคุณเรียนรู้ที่จะอยู่เพื่อคนอื่น พวกเขาก็จะอยู่เพื่อคุณ

Elastic energy:

(english) The energy stored in deformed elastic material (e.g., a watch spring). Elastic energy equals where k is the stiffness, and is the associated deflection. Elastic energy is sometimes called elastic potential energy because it can be recovered when the object returns to its original shape; see potential energy.

When life is giving you a hard time, try to endure and live through it. You must never run away from a problem. Convince yourself that you will survive and get to the other side

เมื่อคุณเห็นการมีชีวิตเป็นสิ่งที่หนักหนาสาหัส ลองพยายามอดกลั้นและต่อสู้กับมัน จงอย่าวิ่งหนีต่อปัญหาใด ๆ ที่คุณเผชิญอยู่ และเชื่อใจในตัวเองว่าสองมือของคุณสามารถทำให้คุณฝ่าฟันช่วงวิกฤตและผ่านมันไปได้

Greenhouse gases

(Environmental Engineering) Gases which trap solar radiation. Of the solar energy entering the earth's atmosphere a portion is reflected back and a portion penetrates onto the earth's surface. The portion reflected back from the earth's surface is at a different wavelength that when it entered. Carbon dioxide and other gases, which pass solar radiation, absorb this reflected radiation, increasing the earth's temperature. This is much like a greenhouse, hence the name.
