Required information A cast-iron tube is used to support a compressive load of 4 kip. Given: $E = 11 \times 10^6$ psi and that the maximum allowable change in length is 0.025% and the outer diameter of the tube is 1.9 in, determine, (a) Allowable inner diameter of the tube (b) Is the value a minimum/maximum? Why? The maximum stress in the member is given as $\sigma_{max}$ (psi)

Step 1
Given that the change in length is 0.025%, we need to convert it to a decimal form by dividing it by 100. 0.025% / 100 = 0.00025 Show more…

A circular tube $A B$ is fixed at one end and free at the other end. The tube is subjected to axial force at joint $B$. If the outer diameter of the tube is 3 in. and the thickness is $3 / 4$ in., calculate the maximum normal stress in the tube.

Normal Stress and Strain
A copper alloy pipe having yield stress $\sigma_{Y}=290 \mathrm{MPa}$ is to carry an axial tensile load $P=1500 \mathrm{kN}$ (see figure part a). A factor of safety of 1.8 against yielding is to be used. (a) If the thickness t of the pipe is to be one-eighth of its outer diameter, what is the minimum required outer diameter $d_{\min } ?$ (b) Repeat part (a) if the tube has a hole of diameter $d / 10$ drilled through the entire tube as shown in the figure part b.

A thin-walled tube with closed ends is pressurized internally. Assume that σ = 150 × 0.25 (MPa). (a) At what value of effective strain will instability occur with respect to pressure? (b) Find the pressure at instability if the tube had an internal diameter of 10 mm and a wall thickness of 0.5 mm.
