- For my medical device, I wish to create a material that is soft and will retain a lot of water. But I also want it to be rigid and can withstand up to 50lbs of force. What material should I use?A current problem in the U.S. Air Force is the neck/shoulder fatigue experienced by pilots. To be able to fly missions at night, the pilots wear night vision goggles, which are attached to the front of the helmet. Unfortunately, these are heavy, causing a large downward torque of the head, which must be counteracted by the neck muscles, which then fatigue. To alleviate this problem, many pilots have started attaching random lead weights to the back of the helmet. Find the appropriate weight that would best balance the head and minimize neck fatigue – You must show your free body diagram. Assumptions: a) center of gravity of goggles is 20 cm in front of neck pivot point, b) load of goggles1.0 kg mass, c) center of gravity of lead weight is 10 cm behind neck pivot point, d) load of bare helmet 3 kg mass, e) center of gravity of helmet is 2 cm in front of neck pivot, f) load of head 4.0 kg mass, and g) center of gravity of head is right at neck pivot point.

- As the lead engineer for a LPG storage project, you are overseeing the design of pressure vesselssuch as those shown below. Identify which test (or tests) is mostsuitable to pick a material and thickness for the spherical shell of the pressure vessel. Why these are the relevant tests. Explain what information these tests provide and why it is important to determining material and thickness.As James orbits, he slams into a space elevator, peals himself off, and gets in. On the way down, he thinks about how much strain his legs (0.3m long) can take. If he has a mass of 45kg, and a diameter of 3cm what is the strain on each leg? Assume compact bone.As an automobile accessory designer, you must choose between two materials for building bulletproof windows. You put each substance to the test by shooting one bullet at it. You discovered that the first glass causes bullets to bounce off the material, while the second causes the bullet to sink into the glass, given the fact that neither substance breaks. Argue on which is the best material to use to make the windows bulletproof.
