A copper bar has an 8 cm radius. If the elastic limit is not exceeded, what force is needed to extend the rod by 10% of its length? Y = 12 × 10^10 N/m².
Added by Elijah H.
Step 1
The original length of the copper bar can be calculated using the formula for the circumference of a circle: C = 2πr, where C is the circumference and r is the radius. Given that the radius is 8 cm, we can calculate the original length as follows: Original length Show more…

A bar of aluminum has a cross section of $1.0 \mathrm{~cm} \times 1.0 \mathrm{~cm}$ $1.0 \mathrm{~cm} \times 1.0 \mathrm{~cm}$ and a length of $88 \mathrm{~cm} .$ (a) What force would be needed to stretch the bar to $1.00 \mathrm{~m}$ ? (b) What is the tensile strain of the bar of aluminum at that point? SSM Example $9-1$
What is the maximum load that could be suspended from a copper wire of length $1.0 \mathrm{m}$ and radius $1.0 \mathrm{mm}$ without permanently deforming the wire? Copper has an elastic limit of $2.0 \times 10^{8} \mathrm{Pa}$ and a tensile strength of $4.0 \times 10^{8} \mathrm{Pa}$.
