Problem 4:Gearbox and compound train gear system are widely used in power transmission systems to change input torquesand revulsions. Your task in a company that manufactures compound gear system box is to determine thenecessary parameters to obtain a required output and securely mounting the gearbox. If the compound gearboxshown in Figure.5 has the following design specifications:BD' FOUTPUTINPUTT3A(ET2Figure.5: Compound gear train system (left), Gearbox securely mounted by clamps (Right)Gear A has 25 teeth, Gear B has 150 teeth, Gear C has 60 teeth, Gear D 120 teeth, Gear E has 15 teethand Gear F has 200 teeth.Input power and speed, respectively, 20 kW and 1500 rpm (clockwise).Your manger asked you the perform the following analysis steps:EDetermine the velocity ratio/gear-ratio of compound gear system.(2. Calculate the output torque and determine its.direction3. Find the required total/hold torque to securely mount the gearbox.4. Explain the use of compound gear instead of a simple gear train (no more than 50 words).5. Consider that rotational motion must be translated from the output gear shaft to another shaft making60° with first shaft. Based on Figure.6, find the required conditions for a constant velocity ratiobetween two joined shafts. OutputInputFigure.6: Universal joint or Hook's joint.
