Answer:

Option A    

Step-by-step explanation:

angles ABD and DBC are complementary                     given

angle ABD=50 degrees                                                   given

angles ABD and DBC = 90 degrees                              def. of complementary

angle DBC = 40 degrees                                                algebra (90-50=40)

angles EBF and ABD are vertical angles               vertical angles postulate

angle EBF is congruent to angle ABD                           def. of vertical angles

angle EBF = 50 degrees                                                def. of congruence

angles EBF and ABF are a linear pair                            def. of linear pair

angles EBF and ABF are supplementary                       def. of linear pair

angles EBF and ABF = 180                                              def. of supplementary

angle ABF = 130 degrees                                                algebra (180-50=130)

angles ABF and EBD are vertical angles                   vertical angles postulate

angles ABF and EBD are congruent                               def. of vertical angles

angle EBD = 130 degrees                                                def. of congruence

angles CBE + DBC = EBD                                                diagram

angles CBE + DBC = 130 degrees               transitive property of congruence                

angle ABD = 90                                            algebra (130-40=90)

B is needed in the process, but the main statement that actually does the justification is A, so option A

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!!
