Chapter 31, Problem 5RQ
The PCM checks for a closed throttle plate each time the engine starts. This becomes the base for all throttle settings and can be viewed by looking at the PID with the throttle closed. Which of the following would not cause an abnormal reading and a higher-than-normal idle speed?
a. A bad TP sensor
b. A bad IAC valve
c. Loose or worn throttle plates
d. Excessive noise in the TP or related circuits

Calculate for the vertical cross section moment of inertia for both Orientations 1 and 2 of a 1 x 1.5 in. horizontal hollow rectangular beam with wall thickness of t = 0.0625 in.
Use the equation: I = ((bh^3)/12) - (((b-2t)(h-2t)^3)/12)
Please answer 'yes' or 'no' and 'is' or 'is not' for the following:
Consider a large 23-cm-thick stainless steel plate (k = 15.1 W/m-K) in which heat is generated uniformly at a rate of 5 x 105
W/m³. Both sides of the plate are exposed to an environment at 30°C with a heat transfer coefficient of 60 W/m²K.
The highest temperature will occur at surfaces of plate while the lowest temperature will occur at the midplane.
