The slenderness ratio is defined as the ratio of length l to the radius of gyration k, represented as l/k. When the slenderness ratio exceeds a value of 100 for a strong slim column, failure by buckling can be expected. Columns of stiffer and more brittle materials will buckle at lower slenderness ratios.
Crusher Reduction Ratio - Mineral Processing & Metallurgy
Crusher Reduction Ratio. I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged ...
Wood Handbook--Chapter 4--Mechanical Properties of Wood
The ratio of the transverse to axial strain is called Poisson's ratio. The Poisson's ratios are denoted by µLR, µRL, µLT, µTL, µRT, and µTR. The first letter of the subscript refers to direction of applied stress and the second letter to direction of lateral deformation. For example, µLR is the Poisson's ratio for

Definition of Ratio
A ratio shows the relative sizes of two or more values. Ratios can be shown in different ways: • using the ":" to separate example values. • using the "/" to separate one value from the total. • as a decimal, after dividing one value by the total. • as a percentage, after dividing one value by …
Dissolution - an overview | ScienceDirect Topics
Dissolution is an important step during preformulation studies because the rate of drug dissolution of a drug will exert a direct impact on bioavailability and drug delivery aspects (Bergstrom et al., 2014).Dissolution can be defined as the process through which drug particles tend to dissolve in the body fluids. Any change in drug dissolution will significantly affect the bioavailability.

Crushing Efficiency Factors - Mineral Processing & Metallurgy
Note that crushing ratios in a ball mill are not well defined, but are believed to range up to 1.5 or even 2.0. In a second series of measurements, the particle size was not uniform—a distribution of particle sizes corresponding to a natural grading was used. Figure 3-18 shows the results compared with efficiency for single-layer crushing.
Trample | Definition of Trample by Merriam-Webster

COMPRESSION AND BUCKLING
A parameter which is employed to group these columns is the slenderness ratio, L e / k. The minimum slenderness ratio Le k min marks the nominal transition from crushing to buckling. If the axial stress, σ, is plotted as a function of slenderness ratio, then the minimum slenderness ratio is the nominal transition from the constant stress for ...

Limiting Reactant Definition in Chemistry
The reason there is a limiting reactant is that elements and compounds react according to the mole ratio between them in a balanced chemical equation. So, for example, if the mole ratio in the balanced equation states it takes 1 mole of each reactant to produce a product (1:1 ratio) and one of the reactants is present in a higher amount than the other, the reactant present in the lower amount ...

About our tests
A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.
