A pair of standard height factor of helical gear is to be designed to transmit a current of 45.455A (at Philippine's set-up). The output shaft rotates 125rpm and the transmission ratio found to be 4.0. for 20°involute system if the helix angle of the gear is 90% of pressure angle design the gear-meshing and if it found not to be satisfied perform the redesign principle. Box and express your final answer all thru in a three decimal point.
