A 40 cubic ft compressor tank container has a gauge pressure of 140 psi and a temperature of 80 °F. The temperature after some time decreases
to 50 °F. Find the final absolute pressure in the tank after the temperature
change. Assume standard atmospheric pressure is 14.7 psi and absolute
temperature is Rº = F° + 460.*
A. 166.24 psi
B. O 146.1 psi
C. O 224.0 psi
87.5 psi

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.
