What is cross sectional area of a bolt?
Cross-sectional area of the tube material is At=10−4m2 and its length is l = 50 cm. The bolt is just taut so that there is no stress in the bolt and temperature of the assembly increases through Δθ=10∘C. Given, coefficient of linear thermal expansion of steel, αb=10−5/∘C. Young’s modulus of steel Yb=2×1011N/m2.
What is the bolt root area?
Root area is based on the root or minor diameter of the threads, and therefore its stress area is smaller than the tensile stress area. Root area is not based on experimental data. It is designed to introduce a factor of safety in thread strength calculations.
What is bolt stress area?
The weakest points in a bolt is the stressed area in the thread root. The stressed area depends on the type of threads – coarse threads reduces the stressed area compared to fine threads.
What is the minor area of a bolt?

What is tensile area of a bolt?
Substituting P = 1 / n results to A t = 0.7854 * [d – (0.9382 / n)] 2, where d is given in mm, and n is given in threads/mm.
What size bolt is between 5/16 and 3 8?

What is the stress area of a bolt?
The weakest points in a bolt is the stressed area in the thread root. The stressed area depends on the type of threads – coarse threads reduces the stressed area compared to fine threads. The stressed area in a bolt can be calculated as. A = (π / 4) (dn – 0.9743/ n)2 (1) where.
What is the tensile stress area of a bolt?
Definition & Formula. Tensile Stress Area of Bolt, often represented by A t, is a physical quantity used to measure the crirical stress area or the mimimum area of threaded section of a bolt.
How do you calculate the cross sectional area of a rectangle?
If the shape is rectangular, measure the width and length of the rectangle. Calculate the cross-sectional area by determining the area of the geometric shape. For a rectangle, multiply adjacent side lengths using this formula: area = length x width. For a circle, the area = (3.14) x radius x radius.
