A structural component is fabricated from an alloy that has a plane strain fracture toughness of It has been determined that this component fails at a stress of 300 MPa when the maximum internal crack length is 4.0 mm. For the same component and alloy, will fracture occur at a stress level of 260 MPa when the maximum internal crack length is 6.0 mm?

Firstly, the water in the dams hold gravitational potential energy as they are above ground level. the gravitational potential energy is then transferred to kinetic energy as it falls, spinning the turbinethe turbine then spins the generator, which is a large magnet surrounded by metal coils. by doing this, the generator generates electricity. in this action, the energy transfer taken place is kinetic to electric energy

What are the choices?
