Deep Drawing Calculator. Calculate the required force to deep draw a piece of sheet metal based on the drawing ratio, sheet thickness, and the ultimate tensile strength of the material. The drawing ratio is a measure of the severity of the drawing operation and is the ratio of the initial blank diameter to the punch diameter.
The D/d Ratio is the ratio of the diameter around which the sling is bent, divided by the body diameter of the sling. Example: A 1/2" diameter wire rope is bent around a 10" diameter pipe; the D/d Ratio is 10" divided by 1/2" = D/d Ratio of 20:1. This ratio has an effect on the rated capacity of slings.
Here is how you can calculate this answer: Find the volume (in m3) of the 12 mm steel rod using the cylinder volume formula: V = π⋅d2⋅l/4 = π⋅ (12×10-3)2⋅12/4 = 1.3572×10-3 m3. Look up the steel's density. For TMT steel bars, it is 7850 kg/m3. Multiply the volume with density to get the 12 mm steel weight:

A ratio of 2 to 1 would be signified by 2:1. A ratio of 1/4 to one would be signified by .25:1. To find the total ratio, use the pulley ratio formula: Ratio = (Radius of Driven Pulley) / (Radius of Drive Pulley) Example: A handcrank is attached to a drive pulley of 2 inches in radius. The belt runs from the drive pulley to a driven pulley.
Friction reduction ratio is the function of the average velocity of fracturing fluid, the gelled agent concentration, and the proppant concentration. Based on the linear regression of 1049 experimental and field data, Lord et al. put forward the following empirical formula to calculate the friction reduction ratio of HPG fracturing fluid (Lord, 1987):

It has been observed that increasing cold rolling reduction increases the r m value, at least up to 90% [34].This effect has been shown in Fig. 5.14.Perhaps the most important parameters in the production of a strong {111} recrystallization texture are the annealing temperature and …
Exploring the D/d Ratio Concept. Simply put, the D/d Ratio refers to the relationship between two diameters: the diameter (D) around which a sling is bent, and the sling's own diameter (d). Think of it as comparing the size of the load or rigging hardware to the sling's thickness. All slings lose capacity when they are bent too much.
