I didnt see the subject that it is for. But this is a question I am stuck on for Air Pollution Sciences. How much faster does a 10-micrometer aerodynamic diameter particle settle than a 5- micrometer diameter particle of the same shape and density? (use stokes law)

On a average work day more than work place firs are reorted

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

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.
