A strain gage rosette is attached to the outside of an open soda can (as shown below). A typical soda can has the following dimensions: 66mm outside diameter, 0.12mm wall thickness with E=70GPA, v=0.3. The can is then sealed and pressurized to 200kPa. Determine the state of stress on the outside surface of the can at the location of the rosette (after it is pressurized). Draw a stress element representing it. Draw Mohr's circle for the state of stress. Label the axes, the stresses you are plotting, the center of the circle, and the radius of the circle. Determine the readings on the three strain gages from your state of stress. Gage e 45 Gage b 45 Gage a

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
