Develop a computer program for the "Gear Transmission Systems" with consideration that each gear designer will have a different view as to what the most important design factors are. The overall design objective is to produce a design which meets all technical requirements for performance and life, at the lowest lifetime cost. Options should be provided for the user to select certain design parameters. The program shall clearly indicate the compliance of the computed output with the standard. All assumptions need to be clearly mentioned. The input to the program could include: Number of teeth pinion and gear Diametral pitch Material Transmitted power Speed Factor of safety Reliability Load characteristics and characteristics of support You may need to include other operational input such as working temperature to determine the different factors. The output of the program may contain but not limited to the followings: gear size contact ratio pitch line velocity transmitted load real factor of safety overall factor of safety gear efficiency sliding velocities angle of approach and recess weight estimations, cost estimation (Not necessary to include if you don't have data)
