10. A steel rod (Es = 210 GPa, dr = 12 mm, ?s = 12 x 10^-6/°C) is held stress-free between rigid walls by a clevis and pin (dp = 15 mm) assembly at each end. If the allowable shear stress in the pin is 45 MPa and the allowable normal stress in the rod is 70 MPa, calculate the maximum permissible temperature drop. a. 14°C c. 28°C b. 20°C d. 40°C

Step 1
A steel rod is held stress-free between rigid walls by a clevis and pin assembly at each end. The rod is initially at a temperature of 15 mm (this seems to be a mistake, as temperature is not measured in mm, but let's assume it's 15°C for the sake of the problem). Show more…

A steel rod 0.450 $\mathrm{m}$ long and an aluminum rod 0.250 $\mathrm{m}$ long, both with the same diameter, are placed end to end between rigid supports with no initial stress in the rods. The temperature of the rods is now raised by 60.0 $\mathrm{C}^{\circ} .$ What is the stress in each rod? (Hint: The length of the combined rod remains the same, but the lengths of the individual rods do not. See Problem $17.85.)$
A steel rod 0.350 $\mathrm{m}$ long and an aluminum rod 0.250 $\mathrm{m}$ long, both with the same diameter, are placed end to end between rigid supports with no initial stress in the rods. The temperature of $f$ the rods is now raised by 60.0 $\mathrm{C}^{\circ}$ . What is the stress in each rod? (Hint: The length of the combined rod remains the same, but the lengths of the individual rods do not. See Problem $17.89 .$ )
The illustration shows a steel rod fixed between two walls. The rod has a length (L) of 10 m and a circular cross-sectional area with a radius (r) of 0.03 m. How much force is generated by the rod on the wall if the temperature increases from 20°C to 40°C?
