The sum of opposite angles are equal, so two of the angles are 45°.  The sum of all angles about the intersection of two lines is 360°.  So the remaining two angles are found by:

α=(360-2*45)/2

α=135°  thus all four angles are:

45°,135°,45°,135°

How do I write this?
den301095 [7]

Answer:

452+(783-546)

Step-by-step explanation:

Add 452 ; 452+

the difference of 783 and 546 ; 783-546

You add in the parentheses so that you're adding 452 to the difference of the two other numbers instead of to 783.

An AISI 1040 cold-drawn steel tube has an OD 5 50 mm and wall thickness 6 mm. What maximum external pressure can this tube withs
lukranit [14]

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!!
