Answer:
A = 2
Step-by-step explanation:
Using 0 for p, we have ...
F(0) = (2·0 +4)/(0 -A) = 4/-A
We want this to be -2, so ...
-2 = 4/-A
A = 4/(-(-2)) = 2 . . . . multiply by A/-2
A = 2
<h3>We know that :</h3>
<h3>Asked :</h3>
A = …?
<h3>Solution :</h3>
A = ½ (a + b) × h
A = ½ (6 + 2) × 3
A = ½ (8) × 3
A = 4 × 3
A = <u>12</u> square units.
Answer:
82.79MPa
Step-by-step explanation:
Minimum yield strength for AISI 1040 cold drawn steel as obtained from literature, Sᵧ = 490 MPa
Given, outer radius, r₀ = 25mm = 0.025m, thickness = 6mm = 0.006m, internal radius, rᵢ = 19mm = 0.019m,
Largest allowable stress = 0.8(-490) = -392 MPa (minus sign because of compressive nature of the stress)
The tangential stress, σₜ = - ((r₀²p₀)/(r₀² - rᵢ²))(1 + (rᵢ²/r²))
But the maximum tangential stress will occur on the internal diameter of the tube, where r = rᵢ
σₜₘₐₓ = -2(r₀²p₀)/(r₀² - rᵢ²)
p₀ = - σₜₘₐₓ(r₀² - rᵢ²)/2(r₀²) = -392(0.025² - 0.019²)/2(0.025²) = 82.79 MPa.
Hope this helps!!
Answer:
y=1
Step-by-step explanation
the x is like a imaginary 1 so 4*x=4-3=1
