An engineer has designed and built a prototype to improve the brake system of a car. What is the next step that the engineer should take in the process

Test the working prototype

Explanation:

After the prototype is built, it is put through basic operational tests and purpose of applicability or performance test

The prototype is also laboratory tested to determine how reliable it is with tests performed to determine the modes of failure. Performance of tests are carried out by subjecting the prototype to stresses beyond its designed stress such as to discover failure modes

The system is however tested in isolation at this stage and the performance and risks of the prototype are quantified after the test, with improvement requirement outlined for modification of the design.

explanation:

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
