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 Δ𝑙 =1.2 𝑚𝑚.𝐸 =200 109𝑃𝑎

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.

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 𝑐𝑚2 occur? Data: 𝐸 =200 𝐺𝑃𝑎

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 Δ𝑑 =0.0062 𝑚𝑚 and an elongation of Δ𝑙 =0.04𝑚𝑚 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.
