Burr 2 |
(english) Roughness left by a cutting operation such as slitting, shearing, blanking , etc. |
Burr Mashers |
(english) Devices used to remove build up on edge of strip after the slitting process. |
Butt-Weld Pipe |
(english) The standard steel pipe used in plumbing. Heated skelp is passed continuously through welding rolls, which form the tube and squeeze the hot edges together to make a solid weld. |
Degree of Freedom: |
(english) A displacement quantity which defines the shape and location of an object. In the two dimensional plane, a rigid object has three degrees of freedom: two translations and one rotation. In three dimensional space, a rigid object has six degrees of freedom (three translations and three rotations). |
Displacement: |
(english) A change in position. A displacement may be a translation a rotation or a combination of those. |
Fixed support: |
(english) In two dimensions, a fixed support restrains three degrees of freedom: two translations and one rotation. |
Modulus of elasticity: |
(english) The proportional constant between stress and strain for material with linear elastic behavior: calculated as stress divided by strain. Modulus of elasticity can be interpreted as the slope of the stress-strain graph. It is usually denoted as E, sometimes known as Young's Modulus Y, or E-Modulus. |
Moment: |
(english) The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple. |
Pin connection: |
(english) In two dimensions, a pin connection restrains two translation degrees of freedom but does not restrain rotation. Since the rotation degree of freedom is unrestrained at a pin connection, it transfers no moment. |
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. |
