A 5 ton load has to be lifted with 2 slings. The horizontal sling angle is 50°, the slings legs have equal length, and the center of gravity is in the center of the load (if not, see Centre of Gravity). Solution to find required sling capacity (or WLL): tons is the VERTICAL Rated Capacity required for EACH sling.

The second equilibrium condition (equation for the torques) for the meter stick is. τ 1 + τ 2 + τ + τ S + τ 3 = 0. When substituting torque values into this equation, we can omit the torques giving zero contributions. In this way the second equilibrium condition is. + r 1 m 1 g + r 2 m 2 g + r m g − r 3 m 3 g = 0.

I'm confused about load combinations in relation to horizontal and vertical loads. Take for example the load combination + on a single footing. Would the engineer then apply a vertical load of on the footing, and then a horizontal load (inducing a moment) to then size the rebar and such in the footing?

Overview of Ball Mills. As shown in the adjacent image, a ball mill is a type grinding machine that uses balls to grind and remove material. It consists of a hollow compartment that rotates along a horizontal or vertical axis. It's called a "ball mill" because it's literally filled with balls. Materials are added to the ball mill, at ...

As the circulating load increases, typically the cyclone underflow density increases, causing the density and viscosity in the mill to also increase. This can lead to excessive mill viscosity, causing the balls to float, leading to a sharp drop in the power draw. The operator can be misled to conclude that the mill is overloaded due to the ...
