Avertical cylinder (fig. p3.227) has a 61.18-kg piston locked with a pin trapping 10 l of r-410aat 10%c, 90% quality inside. atmospheric pressure is 100 kpa, and the cylinder cross-sectional area is 0.006 m2. the pin is removed, allowing the piston to move and come to rest with a final temperature of 10%c for the r-410a. find the final pressure, final volume and the work done and the heat transfer forthe r-410a.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

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.

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.
