## What is the formula to calculate tonnage?

tonnage, in shipping, the total number of tons registered or carried or the total carrying capacity. Gross tonnage is calculated from the formula GT = K1V, where V is the volume of a ship’s enclosed spaces in cubic metres and K1 is a constant calculated by K1 = 0.2 + 0.02 log10 V.

**How do you calculate the force needed to punch a hole?**

The formula is short and relatively simple; Punching Force (PF) = Area x Shear Strength, where Area is the cross-sectional area of the material being punched away and Shear Strength is the shear strength of the particular material being punched.

**How is pressing force calculated?**

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m2.

### How do you calculate structural steel tonnage?

First off, you can calculate the specific weight of steel using the following formula: y=P/V, where P is the weight of a homogeneous body, V is the volume of the combination. The resulting parameter is constant and works only when the steel is of an absolutely dense state and non-porous structure.

### What is tonnage factor?

The tonnage factor provides the mechanism for the conversion from volume of ore to weight of ore. In the English system, the tonnage factor is normally expressed as cubic feet per ton of ore. In the metric system, the tonnage factor is the specific gravity of the ore.

**How do you find the tonnage capacity of a hydraulic press?**

To calculate hydraulic press force, first find piston area from piston diameter. Then multiply the pressure in psi by cylinder area in inches. Divide force in pounds by 2,000 to get force in tons.

**What is steel tonnage?**

Tonnage: Use the following formula to calculate the tonnage required to punch a round hole in mild steel: Punch diameter x Material Thickness x 80 = Tons of pressure required. Example: to punch a 1/2″ hole through 1/4″ thick mild steel. 0.500 x 0.250 x 80 = 10 tons required.

#### How do you calculate structural steel?

#### How to figure out tonnage?

How do we measure the correct cable size?

**How to calculate tonnage [free formula]?**

Tonnage: Circular Areas / Square Footage For circular areas you only need one measurement, the distance across the circle, or diameter (as shown in the image at the right).

**How do I calculate tonnage in progressive stamping?**

Tonnage: Use the following formula to calculate the tonnage required to punch a round hole in mild steel: Punch diameter x Material Thickness x 80 = Tons of pressure required. Example: to punch a 1/2″ hole through 1/4″ thick mild steel 0.500 x 0.250 x 80 = 10 tons required. Use the following formula to calculate the approximate tonnage required to punch a shaped hole in mild steel:
