What will be the minimum diameter of a steel wire which is used to raise a load of 4000N?
9. What will be the minimum diameter of a steel wire, which is used to raise a load of 4000N if the stress in the rod is not to exceed 95 MN/m2? And D = 7.32.
How do you find the diameter of a shaft?
P = 2πNT /60 . You can find out the Torque (T). t ( shear stress) . by this equation you can find out the Diameter of the shaft (D).
What will be the minimum diameter of a steel wire?
Diameter of steel wire would be 7.3 mm.
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 calculate shaft diameter from torque?
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 calculate inner diameter from outer diameter and thickness?
Hi Karla, to find the inner pipe diameter, you need to subtract 2 times the wall thickness, 3/16, from the outside diameter of 2.
How do you calculate maximum allowable stress?
Divide the yield strength by the factor of safety to calculate the allowable stress. For example: allowable stress of A36 steel = 36,000 psi / 4.0 = 9,000 pounds per square inch.
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 maximum stress of a beam?
The maximum shear stress occurs at the neutral axis of the beam and is calculated by: where A = b·h is the area of the cross section. We can see from the previous equation that the maximum shear stress in the cross section is 50% higher than the average stress V/A.
How do you find the DIA of a bearing?
You should wiggle the calipers inside the bearing inner ring to make sure they sit across the widest part. Repeat the process using the external measurement side of the caliper to calculate the outer diameter of the bearing. This time, roll the calipers in a closing direction to obtain the outer diameter measurement.
How is inner and outer dia calculated?
Calculating the internal diameter depends on the outside diameter and the thickness of the outer circle. Find the total diameter of the object in question by taking a measurement from the outside wall of one side (the point of origination) straight across to the outside wall of the other side (the endpoint).
How do you find the inside diameter of a pipe from the outside diameter?
Measure circumference using a flexible tape and divide the outside circumference by 3.1415. Here the circumference is about 1/32″ (0.03″) less than 6″ = 5.97″. So 5.97 ÷ 3.1415 = 1.900″ diameter – 1 1/2″ nominal pipe.
How do you find the outside diameter?
Measure or calculate the outside circumference of the pipe. Then divide that amount by pi, usually rounded to 3.1415. The result is the outside diameter of the pipe.
How do you calculate stress factor of safety?
Factor of safety=Ultimate Load (Strength)/Allowable Load (Stress)
How do you calculate maximum allowable stress in ASME?
The Maximum Allowable Working Pressure (MAWP) is 580 psi gauge. Material is carbon steel SA-192.
For tubing up to and including 5 in O.D., use equation 1.1 above.
- P = [580 psi]
- D = [2.75 in]
- e = 0 (strength welded)
- S = [11,800 psi] at [650°F])
- t = 2.75 x 580 + 0.005 (2.75) + 0 2 (11,800) + 580.
- t = 0.079 in.
How do you calculate stress in steel?
We calculate the stress, using the stress formula: σ = F/A = 30*10³ / (1*10⁻⁴) = 300*10⁶ = 300 MPa . Finally, we divide the stress by strain to find the Young’s modulus of steel: E = σ/ε = 300*10⁶ / 0.0015 = 200*10⁹ = 200 GPa .
