Slenderness Ratio is Basically a Ratio to decide if the Steel angle being used is acceptable for particular loads or not.
There is no such allowable limit of slenderness ratio For a particular angle unless it is designed for a particular load.
Slenderness Ratio indicates the buckling of the Steel angle. Less the Slenderness Ration more stronger is the Steel angle.
I am an Engineer ( specialised in Towers for Transmission of High Voltages. In Our Case, we use three types of slenderness ratio .
For Main Members it Should Be less Than 120
For Bracing etc it should be less than 150
and for redundant members( No load) < 200

What is Poisson's ratio for stainless steel?
Poisson's Ratio of stainless steel
What is the ultimate stress of mild steel?
Allowable stress would normally refer to design using Allowable Strength Design, also known as working strength design. In this the allowable stress is usually a fraction of the yield strength and can be different for uniform tension and bending. Typically mild steel has a yield strength of about fy=250MPa with allowable stresses in Tension, 0.6fy=150MPa Bending, 0.66fy=165MPa
What is the allowable stress of steel guaranteed by Chinese standard Q235?
Fy = 235Mpa Fu = 400Mpa
What is slenderness ratio structural engineering?
The slenderness ratio is the ratio between the height or length of a structural element (such as a column, or strut) and the width or thickness of the element. For example, if a rectangular column is 6m high, and 400mm by 600mm in cross-section, then its slenderness is 6000/600 = 10 in one direction and 6000/400 = 15 in the other direction. The higher the slenderness ratio, the more slender the structural element is. How slender a structural element is allowed to be depends upon the material it is made from. Steel can be more slender than concrete, for example. In structural engineering calculations, the slenderness is often denoted as the element's "effective" length divided by something called the radius of gyration. The radius of gyration is a measure of the average distance of the material from the centroid (centre of gravity) of the element's cross section. This can be calculated as r = (I/A)0.5, where I is the second moment of area, or second moment or inertia, of the cross section and A is the area of the cross section. The effective length of an element is determined by how it is fixed at its ends. The effective length is the length of the column that will form half a sine wave if it buckles. If it is "pinned", or has hinged ends, the effective length is the true length of the element. If it is a cantilever (fixed at one end but free at the other), the effective length is twice the true length. If it is fully fixed at both ends the effective length is 0.7 times the true length, but this is in reality very difficult to achieve, so often a real structural element is considered to be only nominally fixed and the effective length is taken to be 0.85 times the true length.
Purpose of hip bracing in steel towers please answer it in detail as much as you can?
1. for support of bracing 2. reduce the torsion effect. 3.reduce the slenderness ration Regard Ravi
What is the allowable limit of slenderness ratio in aluminum?
You have to know that the slenderness ratio only takes into account the shape of the column. So because of that, the slenderness ratio is the same for steel, aluminium, wood, etc. The formula KL/r where K is the equivalent length factor, L the length of the column and r the radius of gyration which is sqrt(I/A), should always stay under 200. If not, you must redesign...

Where do you buy carbon steel?
Steel by definition is carbon steel. The only thing that varies is the ratio.

What determines the steel ball ratio of a ball mill?
The steel ball ratio in a ball mill is determined by the material being milled and the grinding conditions. Generally, a higher steel ball ratio results in more effective grinding and finer particles. However, the optimal steel ball ratio may vary depending on the specific milling process and desired outcome.
What is the ratio of 2500 pounds for 1 ton of steel?
There are 2000 pounds in 1 ton of steel, so the ratio is 2000:1.
