Step 1
The stress (σ) is given by the formula: σ = P / A Given: P = 10 kN = 10,000 N A = 10 mm^2 = 10 * 10^-6 m^2 Substituting the values into the formula: σ = 10,000 N / (10 * 10^-6 m^2) Show more…

A 9 -m length of 6 -mm-diameter steel wire is to be used in a hanger. It is observed that the wire stretches 18 mm when a rensite force $\mathbf{P}$ is upplied. Knowing that $E=200$ GPa, determine $(a)$ the magnitude of the force $P, 1$ (b) the corresponding normal stress in the wire.
Two steel wires, each having a cross-sectional area of $2 \mathrm{mm}^{2}$ are tied to a ring at $C,$ and then stretched and tied between the two pins $A$ and $B$. The initial tension in the wires is $50 \mathrm{N}$. If a horizontal force $\mathbf{P}$ is applied to the ring, determine the force in each wire if $P=20$ N. What is the smallest force $P$ that must be applied to the ring to reduce the force in wire $C B$ to zero? Take $\sigma_{Y}=300$ MPa. $E_{\mathrm{st}}=200 \mathrm{GPa}$.
P3 The force applied at point E causes point C to displace downward 25 mm. Calculate the average normal strain in wires AH, CG, and DF.
