True power, measured in watts, represents the actual power consumed by electrical devices to perform work, while reactive power, measured in volt-amperes reactive (VAR), is the power that oscillates between the source and load without being consumed. The distinction lies in the fact that true power contributes to the actual energy consumed, whereas reactive power supports the voltage levels necessary for active power to do useful work. Understanding these concepts is crucial for optimizing electrical systems and improving energy efficiency. Resources like the provided links offer further clarification on these terms. Mastery of true and reactive power is essential for effective electrical engineering and energy management.
TL;DR: determine the internal force of member OA
Hi I'm struggling with this problem. I have calculated the angle to be 45 degrees with tan(theta) = a/a. A is a roller which only has Ay and O has Ox & Oy as a fixed pin. (see fbd.png) is my FBD correct?
