Question details

Page 2 of 2 The day before the space shuttle launch, your engineering team inspects the high-strength stee support beams of the launch structure that hold the shuttle upright. Using radiography, you detect an interior crack of 3 cm length (2a 3 cm) in a beam that is expected to be under a 100 MPa tensile stress during the launch. That steel has been supplied to you with stated fracture toughness Ke-90 MPa m1/2, yield strength ơ,-700 MPa, and elastic modulus E-200 GPa. Should you cancel the launch, or will thesupport structure maintain its integrity during liftoff? 5.
