(a) For an Electro-hydrostatic actuator (EHA) system, the manufacturer found that the reliability of the actuator system, as a function of operating hours (). can be represented by the following hazard function. h(t) = 1.25 x 10-6 + 5.81 x 10-16 43.2 w Produce a rough sketch of the hazard function in the form of a bathtub curve and clearly identify and label the failure modes of the Electro- hydrostatic actuator (EHA) system. (7 marks) (ii) Calculate the reliability R(t) of the system at time t = 3500 hrs - for student with ID that ends in an odd number. time t = 4000 hrs - for student with ID that ends in an even number. (10 marks) Page 3 of 8 ii) Calculate the hazard rate due to wear out failure hz(t) of the system at: . time t = 3500 hrs - for student with ID that ends in an odd number. time t = 4000 hrs - for student with ID that ends in an even number.
