A structural component in the form of a wide plate - id10068211 от gracebuffum 07.01.2020 16:23

Question

Engineering: A structural component in the form of a wide plate is to be fabricated from a ferritic steel alloy (stress-strain curve below) that has a plane strain fracture toughness of 98.9 MPa . The flaw size resolution limit of the flaw detection apparatus is 3.0 mm, that is flaws below this size cannot be detected. If the design stress is taken to be the 0.5% yield strength with a factor of safety 1.2, determine whether or not a critical flaw for this plate is subject to detection. Take the value of the

a) 15.8 ms-1b)869 mStep-by-step explanation:We have to obtain the resultant velocity by the Pythagorean theory;R^2= V1^2 + V2^2Where R= resultant velocity of the boatV1= velocity of the boatV2= velocity of the flowing riverThus;R= √V1^2 + V2^2R= √15^2 + 5^2R= √225 + 25R= √250R= 15.8 ms-1B) from v= s/tWherev= velocity (resultant velocity in this case)s= distancet= time (55 secs)s= vts= 15.8×55s= 869 m...
