Does car air conditioner cost oil for cooling or heating? Do you really know?

The compressor of the car air conditioner is driven by the engine. Turning on the air conditioner is equivalent to increasing the engine load. Of course, it will consume more fuel. The fuel consumption of the car when the air conditioner is turned on is higher than when it is not turned on, and the fuel consumption is not increased when heating.

The influence of machining on fatigue life

The residual compressive stress introduced by shot blasting/shot peening is a percentage of the final tensile stress strength, and this ratio increases as the strength/hardness of the part material itself increases. High-strength/hardness metals are more brittle and more sensitive to surface defects. Shot blasting/shot peening will allow these high-strength metals to be used in fatigue-prone working conditions. Aircraft landing gear is usually designed with a fatigue strength of 300 ksi (2068 MPa), combined with shot blasting/shot peening.
