What is tension? (article) | Tension | Khan Academy

It's important to note here that tension is a pulling force since ropes simply can't push effectively. Trying to push with a rope causes the rope to go slack and lose the tension that allowed it to pull in the first place. This might sound obvious, but when it comes time to draw the forces acting on an object, people often draw the force of ...

7 common tle fencing mistakes

 · 1. Corner posts are undersized, or not deep enough. This ranks as the top mistake in fencing, be it barbed, hightensile wire or woven wire. The main issues are undersized posts and corner posts not set deeply enough, particularly in sandy or soft soils. Gerrish, who has clients in 43 states, says, "the depth in the ground should be equal to ...

Shear/Tension capacity of rebar?

 · Your resistance, is this case, will be limited by the steel shear strength and the pryout shrength of the anchor. The steel strength, phiVs=phi**As*min (fu, ) for ASTM A615 Gr60 rebar/ phi=, fu=90 ksi, fy=60ksi. Depending on your geometry, the shear strength could be limited by the pryout strength.

General Principles Processes of Isolation of Metals

A magnetic separator consists of a belt moving over two rollers, one of which is magnetic. The powdered ore is dropped on the belt at the other end. Magnetic portion of the ore is attracted by the magnetic roller and falls near to the roller while the nonmagnetic impurity falls farther off Chemical Methods
