List of examples

Example 1

Find the diameter of a steel rod with a length of 1 m, if it is stretched by a force P = 65 kN, and its elongation $Δ 𝑙 = 1.2 𝑚 𝑚 . 𝐸 = 200 \cdot 109 𝑃 𝑎$

Show example

Example 2

Calculate the minimum diameter of the reinforcing steel rod with a design strength of R=205 MPa, subjected to a tensile force of N=10 kN.

Show example

Example 3

At what value of compressive force P did the relative shortening $𝜀 = - 0.0007$ of a steel rod with a cross-sectional area $𝐹 = 10 𝑐 𝑚 2$ occur? Data: $𝐸 = 200 𝐺 𝑃 𝑎$

Show example

Example 4

A steel rod with a diameter of d=32 mm and a length of l=35 cm was subjected to tensile stress with a force of P=135 kN. The strain measurements showed a decrease in diameter of $Δ 𝑑 = 0.0062 𝑚 𝑚$ and an elongation of $Δ 𝑙 = 0.04 𝑚 𝑚$ over a measured section with a length of L=5 cm. Calculate the modulus of elasticity E and Poisson's ratio $𝜈$ for the material of the rod.

Show example

Example 5

Calculate the stress in a flat bar 90×8 mm, weakened by holes for rivets with a diameter d=16 mm, subjected to a tensile force N=84 kN.
