Delta rosette
Rectangular rosette
5. For each strain gage rosette, calculate the corresponding ? 1 , ? 2 , and ?max using the
measured ?1 and ? 2 . The Youngs modulus (E) and Poissons ratio for steel are 30×106
psi and 0.25 respectively.
6. Calculate the theoretical ? 1 , ? 2 , and ?max using the thick and thin-walled pressure
vessel equations as described below.

THIN-WALLED PRESSURE VESSEL EXPERIMENT
Lab Report
1. Summary (0.5/12)
2. Results (1/12)
The results of the pop can experiment are as follows:
Diameter before opening: 2.6005 inches
Strain value: ?840 ×10?6 in/in
Wall Thickness: 0.0038 inches
Calculate the pressure based on the measured strain
(E and ? for aluminum are 10×106 psi and 0.33 respectively)
3. Discussion (1/12)
1. Do some research to see if you could find some information on the range of pressure
inside the beverage can and comment on your results.
2. A circular shaft with radius r is subjected to a torque T. The modulus of elasticity and
Poisson’s ratio of the shaft are E and ? respectively. Show how a single strain gage
mounted in the 450 direction with respect to the longitudinal axis can be employed
to determine the applied torque. In other words, write T in terms of E, ? , r, and ?,
where ? is the reading of the strain gage.
