Tension-leg platforms (TLPs) are used for oil and gas exploration under deep-sea conditions. The reliability of TLPs under impulsive loading was assessed in Reliability Engineering and System Safety (Jan. 2006). The researchers examined several random variables that contribute to the impulsive force under dynamic loading of a TLP. One variable, tide and surge stress until failure (measured in MPa), was assumed to have a uniform distribution over the interval (4, 5). Find and graph the hazard rate for this variable.
