For a component fabricated from a given brittle alloy with a maximum internal crack length of 1.0 mm, fracture results at a stress of 520 MPa (under Mode I plane strain condition). For this same component and alloy (and same dimensionless parameter Y), compute the critical internal crack length at a stress level of 380 MPa.

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information
