Answer:
The answers are
The average stress = 20000 lb/in²
The maximum tensile stress immediately adjacent to the hole
= 31076.92 lb/in²
Explanation:
To solve the question we have
Weight of tensile load = 30,000 lb
Width of steel bar = 4 in
Thickness of steel bar = 1/2 in
Average Stress = Force/Area
Size of hole drilled = 1.0 in diameter
Available width at cross section where the 1.00 in diameter hole is drilled =
(4 - 1) in = 3 inches
Cross sectional area at the point of reduced cross section due to the drilled hole = Width × Thickness (Since the item is a flat bar)
= 3 in × 1/2 in = 1.5 in²
Therefore Stress = (30000 lb)/(1.5 in²) = 20000 lb/in²
the maximum tensile stress immediately adjacent to the hole.
Bending stress = where
0.5*30000/I = 11076.92 lb/in²
Max stress = 31076.92 lb/in²
The Otto Cycle can be used to describe how an internal combustion engine works, which allows your car to run by just filling it up with gas. <span>Each of the numbers shown in the figure (1 through 6) represent one stage of the Otto cycle, or one step of the internal combustion process. The common automobile engine is called a “4 Stroke Engine” because it has 4 strokes, which are the Intake Stroke, Exhaust Stroke, Compression Stroke, and Power Stroke. The “Combustion Process” shown in the Otto Cycle in the figure occurs between Strokes 3 and 4, and the “Heat Rejection” shown in the figurea occurs between Strokes 3 and 4.</span>
