How do you find the minimum diameter of a shaft?
For example the circumference of the shaft is 600 cm. Then divide 600 to 3.142. The result will be its diameter.
How do you measure the diameter of a solid shaft?
Inputs that we need to calculate shaft diameter
- τ = Torsional stress induced at the outer surface of the shaft (Maximum Shear stress).
- r = Radius of the shaft.
- T = Twisting Moment or Torque.
- J = Polar moment of inertia.
- C = Modulus of rigidity for the shaft material.
- l = Length of the shaft.
How do you find a diameter?
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.
What is the diameter of shaft?
The shaft diameter is defined as the diameter of the hole in the iron laminations that contains the shaft, as indicated with the red arrow in Fig. 1 (and not as the actual diameter of the mechanical shaft, which can be much smaller).
How do you calculate Rod dia?
Measure the length (L, in cm)of the rod and use the formula, V = (pi)r^2*L. Find out r (radius in cm) and double it to get the diameter, cm.
How do you measure the diameter of a steel bar?
Consider a steel bar with diameter D and Length is L. Here, D is steel diameter in mm, and the density of steel is in kg/m3. To make constant value in the same unit we will convert Dia.
| Dia of Steel Bar | Length | Unit Weight |
|---|---|---|
| 16 mm | 1 m | 1.58 kg/m |
| 20 mm | 1 m | 2.46 kg/m |
| 25 mm | 1 m | 3.87 kg/m |
| 32 mm | 1 m | 6.32 kg/m |
How do you find the maximum and minimum principal stress?
Principal stress and maximum shear stress calculator was developed to calculate principal stresses, maximum shear stresses, stress angles and Von Mises stress at a specific point for plane stress (σz=τzx=τzy=0).

What is minimum stress?
The maximum stress refers to the maximum tensile stress while the minimum stress refers to the minimum compressive stress. The stress range was taken as the absolute difference between the maximum and minimum stress.
How do you find the shaft diameter of a power?
- From the formula: power = 2*pi*RPM*Torque/60.
- Find Torque, the use following to find dia.
- Torque = pi/16 * Shear Strength * cube of shaft diameter.
How do you find the diameter with the area?
Divide the area (in square units) by Pi (approximately 3.14159). Take the square root of the result (Example: 310.56). This is the radius. Now double the radius to get the diameter (Example: 621.12 meters).
How do you measure diameter with a ruler?
Measure just the radius of the circle if it is very large. The radius is the distance from the center to any point on the circle. Multiply the radius by two to produce a measurement for the diameter.
How do you find the diameter of a circle without the radius?
If you don’t have the radius, divide the circumference of the circle by π to get the diameter. If you don’t have the radius or the circumference, divide the area of the circle by π and then find that number’s square root to get the radius. Then, you can just multiply the radius by 2 to find the circle’s diameter.
How do you calculate torque needed to rotate a shaft?
To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r). If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm.
What is the diameter of a curtain rod?
between 1-3 inches
Common curtain rod diameters are typically between 1-3 inches, depending on the weight of your curtains.
How do you calculate the change in diameter of a rod?
Calculate the longitudinal strain and Poisson’s ratio for brass given that Y for the brass is 9 × 1010 N/m². Given: Diameter of rod = D = 6 mm, Radius of wire = 6/2 = 3 mm = 3 × 10–3 m, Load F = 5 × 103 N, Change in diameter = d = 3.6 × 10–4 cm = 3.6 × 10–6 m, Y for the brass is 9 × 1010 N/m².
How do I calculate how much concrete I need?
Essentially you are solving for volume and then converting to cubic yards. For concrete, the formula for volume is as follows: length x width x thickness.
Here’s what the math looks like for a 10′ by 10′ concrete patio:
- 10 x 10 = 100 square feet.
- 4 ÷ 12 = .33.
- 100 x .33 = 33 cubic feet.
- 33 x .037 = 1.22 cubic yards.
How do you calculate the weight of mild steel round bar?
Weight is calculated by multiplication of volume and its density. Volume of round bar is equal to πD^2/4. H and its density is equal to 7850kg/m3, then its weight, Weight = πD^2/4.
How do you find the diameter of rebar?
You can multiply the bar size by 1/8 to get the nominal diameter in inches. For example, #8 rebar = 8/8 inches (or 1 inch) in diameter. Common measurements indicate the weight, nominal area, and nominal diameter.
How do you calculate the number of steel bars?
How to calculate number of steel bars in column
- Put that percentage of steel and Gross area of column in Load formula.
- Determine the permissible stress in steel in compression.
- Calculate Area of Steel required.
- Calculate No. Of bars = (area of steel÷area of a single bar).
What is nominal diameter of steel bars?
Nominal diameter may be defined as the dimension of the diameter (in mm) of round bar. In case of deformed bars, the nominal diameter is taken equivalent of that of a plain bar having the same mass per unit length as the deformed bar.
