A PE may sign reports containing debatable but defensible engineering judgments, provided she documents her evaluation and is satisfied the assumptions meet applicable standards.
2. Two masses, 3 kg and 7 kg, are connected by a string over a frictionless pulley (Atwood machine). What is the acceleration of the system?
a = (m2−m1)g/(m1+m2) = (7−3)×9.81/10 = 3.92 m/s².
3. A state engineering board typically has the authority to do which of the following?
State engineering boards are regulatory agencies empowered to discipline licensees, including revoking or suspending PE licenses for violations of the practice act.
4. A project requires $200,000 now and yields $50,000/year for 6 years. At MARR = 10%, (P/A,10%,6)=4.3553, the net present value is:
NPV = −200,000 + 50,000(4.3553) = −200,000 + 217,765 = +$17,765.

BOD measures the dissolved oxygen consumed by aerobic biological organisms decomposing organic material in water at 20°C over 5 days.
6. A Carnot refrigerator operates between −20°C and 30°C. What is its coefficient of performance (COP)?
COP_refrigerator = T_L/(T_H − T_L) = 253/(303−253) = 253/50 = 5.06.
