Dear Current Administrators of TBA, Stop erasing posts and topics. All of you. As a regular of TBA who loved it dearly, you have no idea how much it kills me that so many topics were left to the trash without member consent. And it wasn't just drama posts -some of you deleted any post that you didn't like, from roleplays, from anything...you deleted the entirety of A Very Potter Roleplay, as an example. As the creator of that roleplay, I realize it was somewhat of a failure, but the fact that it was erased without my consent is upsetting, and there were a few members who enjoyed it. I realize that there were some things posted on TBA that many of us are not proud of. Drama and the like. But even with that drama, TBA was so, so, important to me, and others. Yet, certain moderators have ignored this and have erased topic upon topic -that showed in the Administrator history. Even if you say it was only a single topic or a single post, the forum has been trimmed down. You say this is only "cleaning up the forum," but it's erasing our history, and I won't stand for it. To those of you who've returned to this forum only to remove things periodically, please stop. It simply isn't fair to those of us who are nostalgic and like looking back, and I know I don't speak of myself alone. With all due respect, LL.

The concept of a stress on the body cross-sectional area inside the unit to withstand the forces called stress. Stress caused by the external force is called stress work stress, in the absence of external force equilibrium conditions inside an object called internal stress (such as tissue stress, thermal stress, preserved after the end of the process of residual stress ... etc).

When the two mechanical properties, the metal external force (load) in certain temperature conditions, the ability to resist deformation and fracture mechanical properties of materials referred to as metal (also known as mechanical properties). The loads of metallic materials take many forms, it may be a static loads, dynamic loads may be, including individually or simultaneously subjected to tensile stress, compressive stress, bending stress, shearing stress and torsional stress, as well as friction, vibration, impact and so on.

Mechanical properties of metallic materials is the main basis for the design and selection of parts when. Applied load different properties (such as tensile, compression, torsion, impact, cyclic loading, etc.), the mechanical properties of metallic materials required will be different. Common mechanical properties include: strength, ductility, hardness, toughness, impact resistance and fatigue limit several times and so on.discount stainless steel for sale
