A one-dimensional consolidation test was performed on a sample, 0.75 in high, taken from a field clay layer. During the test, drainage was allowed at the upper and lower boundaries. It took the lab sample 15 minutes to reach 50% consolidation. a. Determine the coefficient of consolidation, cv b. If the clay layer in the field has the same drainage condition as the lab sample, calculate how many days it will require the 10-feet clay layer to achieve 50% and 90% consolidation, respectively.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
