The permeability of a semi-impervious soil was evaluated in a falling head permeameter whose head decreased from 40 to 15 inch (100 – 38 cm) in 5 min. The body diameter was 5 in (13cm), the standpipe diameter was 0.1 inch (0.3cm) and the sample length was 2 in (5cm). What was the permeability of the soil in SI units and US units?

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
