A steam-powered lift system (figure) leverages steam flowing through a pipeline at 1 MPa and 400°C to lift objects using a simple piston-cylinder configuration. To lift an object, it is placed on the piston and then the throttling valve is opened. Steam slowly flows into the well-insulated cylinder from the pipeline and lifts the object to the desired height, after which the valve is shut. The massless piston has a cross-section of 100 cm² and the atmospheric pressure is 100 kPa. A. If the cylinder is initially evacuated, what is the final temperature of the water in the cylinder after lifting a 2 kN object? B. How much water, in kg, is needed to lift the 2 kN object 10 m? m Steam line

Given that the time constant's theoretical value is 150.8s, and the percentage error is 0.5%, what is the time constant's experimental value?
You are testing a long-dwelling catheter for its biological response using a rat model. After implantation for 4 months you explant the catheter material and surrounding tissue. Histology shows the catheter material surrounded by a thin layer of aligned collagen that is, in turn, surrounded by numerous polymorphonuclear cells. What has occurred? Describe the short term and long term events that led to this outcome. Note: the fact that this is a rat model rather than a human is not the issue - the model is fine.
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.

Learning Goal: To calculate the maximum allowable stresses in pressure vessels, compute the minimum allowable thickness of pressure vessels to meet certain constraints, and observe and compare properties of different pressure vessel shapes. Engineers are considering two possible vessel shapes for storing fuel. One shape is cylindrical and the other is spherical. Each vessel would be constructed out of the same material such that its hoop stresses and longitudinal stresses would be no greater than 120 MPa. The cylindrical pressure vessel has an inside diameter of de = 800 mm and a thickness of te = 25.0 mm. The spherical pressure vessel has an inside diameter of ds = 650 mm and a thickness of t = 11.0 mm. ▼ Part A - Maximum allowable pressure in the cylindrical pressure vessel Determine the maximum allowable pressure, pc,max, in the cylindrical pressure vessel.
