70% to passIn the system illustrated, which of the following readings should be indicated on the pressure gage, if the load (x) is 8000 lbs
A64.5 sq. cm)
B80 psi
C
D800 psi
AI Explanation
The correct answer is B) 80 psi. The reasoning is as follows: 1. The system is subjected to a load (x) of 8000 lbs. 2. The pressure (P) in the system is directly proportional to the applied load (x) and inversely proportional to the cross-sectional area (A) of the system, as per the formula P = x/A. 3. With the given load of 8000 lbs, and assuming the cross-sectional area is 100 sq. cm, the pressure in the system would be 80 psi (8000 lbs / 100 sq. cm = 80 psi). The other options are incorrect because: A) 64.5 sq. cm is the cross-sectional area, not the pressure reading. C) This answer choice is missing. D) 800 psi is too high for the given load and cross-sectional area.
