13.a)In the late 1960s. Ford designed a small car Pinto and brought it into market at a rapid pace. The gas tank was between the rear axle and the bumper. The prescribed rear impact tests have been conducted and the design was found to be alright. The gas tank caught fire at an impact very marginally higher that the value stipulated in the impact test.
