An aircraft engine component has a volume of 2.1 ft3. (a) Find the weight of the piece when it is made of steel (iron)
(b) If the same piece is made of aluminum, what is its weight?
Weight Density of Aluminum = 168 lb/cu ft.
Weight Density of Steel or Iron = 490 lb/cu. ft.

The weight of engine component when it is made by steel is 1029 lb and when it is made by aluminum then the weight of engine will be 352.8 lb

Explanation:

The given volume of aircraft engine = 2.1 ft^3

The density of steel or iron = 490 lb/cu. ft.

The density of Aluminum = 168 lb/cu ft.

Now we have to find the weight of the engine component when it is made up of steel and aluminum.

Therefore, weight can be determined by multiplying the density with volume.  

(a)Weight in the case of steel = Density × Volume

= 490 × 2.1

= 1029 lb

(b)Weight in the case of aluminum = Density × Volume

= 168 × 2.1

= 352.8 lb

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
