## Comments by Grader while editing the engine, oe has to followup the equal number of decimal places throughout the file. Also in 3D meshing of the bracket, there should not be any rotating quads in the model which will disrupt the whole mesh flow. hence, avoid them. ## Objective: Calculate the speed of the sound in steel…
