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 find the DIA of a rod?
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 is shaft calculated?
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.
How do you calculate factor of safety?
Factor of safety=Ultimate Load (Strength)/Allowable Load (Stress) As understood from the above equation the allowable stress is always less than the ultimate failure stress. Hence, the factor of safety is always greater than 1.
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.
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 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.
| 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 determine the size of a rod?
Note: Length of TMT Steel rod will be 12 meters or 40 feet.
Calculate the weight of the TMT rods in bundles as per size.
| TMT Size | TMT Rods Per Bundle | TMT Weight Per Bundle |
|---|---|---|
| 12mm (1 Bundle) | 5 | 53.4 Kg |
| 16mm (1 Bundle) | 3 | 56.88 Kg |
| 20mm (1 Bundle) | 2 | 59.2 Kg |
| 25mm (1 Bundle) | 1 | 46.2 Kg |
How do you measure a rod end?
It is simply a count of the number of threads per inch measured along the length of the threaded rod. The diameter of the outer edge of thread represents the Thread Size. You are aiming for the same measurement location when measuring the diameter of a female rod end.
What is a shaft diameter?
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 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 of a circle from 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 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.
What is bending equation?
What is the Bending Equation? The axial deformation of the beam due to external load that is applied perpendicularly to a longitudinal axis is called the Bending Theory. The bending equation stands as σ/y = E/R = M/T.
How do you calculate bending stress of a shaft?
If a shaft diameter d is subjected to bending moment M, the bending stress (σ b) induced in the shaft is given by:
- σ b = ( 32 M π d 3 )
- σ b = ( 16 M π d 3 )
- σ b = ( 32 M π d 2 )
- σ b = ( 64 M π d 4 )
What is bending stress formula?
The bending stress is computed for the rail by the equation Sb = Mc/I, where Sb is the bending stress in pounds per square inch, M is the maximum bending moment in pound-inches, I is the moment of inertia of the rail in (inches)4, and c is the distance in inches from the base of rail to its neutral axis.
How do I calculate wire size?
FAQ
- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm2.
