Fun with a helium balloon A loosely filled balloon contains 4.5 liters of helium gas at atmospheric pressure (PA = 101 kPa) and room temperature T = 20 C. The gas in the balloon is then heated to body temperature, 37 C, by a student. (a) The pressure inside the balloon changes very little during the heating process. What is the change in the volume of the balloon? (b) How much work does the expanding balloon do on its environment?...

Problem #1 A cylindrical rod of copper (E 110 GPa) having a yield strength of 240 MPa is to be subjected to a load of 6660 N. If the length of the rod is 380 mm, what must the diameter be to allow an elongation of 0.50 mm? A cylindrical specimen of some alloy 8 mm in diameter is stressed elastically in tension. A force of 15,700 N produces a reduction in the specimen diameter of 5 10-3 mm. Compute...

(17 points) During a percutaneous angioplasty the vessel wall is expanded by inflating a balloon. At a certain moment during inflation the internal pressure was at p 0.2 MPa-while the internal radius of the vessel wall increased by 10% from 1 .5 m m. At the same state, the wall thickness decreased from 0.31 mm down to 0.28 mm, Assuming that the tength of the balloon and the length of the vessel wall in contact with the balloon do not...
