What is normal operating coolant temperature?
Expert Solution & Answer
To determine
State the normal operating temperature of a coolant.
Explanation of Solution
A thermostat is referred as a temperature-controlled valve located at the engine coolant exit on most engines to control the minimum normal operating temperature. It is used to control the normal operating coolant temperature between high-temperature and low-temperature extremes.
The coolant temperature usually depends on the thermostat rating. The engines equipped with a

- 1. The rotating steel shaft is simply supported by bearings at points of B and C, and is driven by a spur gear at D, which has a 6-in pitch diameter. The force F from the drive gear acts at a pressure angle of 20°. The shaft transmits a torque to point A of TA =3000 lbĘ in. The shaft is machined from steel with Sy=60kpsi and Sut=80 kpsi. (1) Draw a shear force diagram and a bending moment diagram by F. According to your analysis, where is the point of interest to evaluate the safety factor among A, B, C, and D? Describe the reason. (Hint: To find F, the torque Tд is generated by the tangential force of F (i.e. Ftangential-Fcos20°) When n=2.5, K=1.8, and K₁ =1.3, determine the diameter of the shaft based on (2) static analysis using DE theory (note that fatigue stress concentration factors need to be used for this question because the loading condition is fatigue) and (3) a fatigue analysis using modified Goodman.
