A helical cast steel with 30 helia angle has +o tanmiz 35 KW at 1500 Y An. Gear has 24 teeth , 20 full depth. The Static stress for Cast Steel maybe taken as 56 Mpa. The width of face may be taken as 8 times th module. Assume: Cs al, Ep=E=200GPa Ges=300 MPa, be =60 MPa, C=40. Calculate: WA, WN, m, b, VR, Tp Ta Dp, Da sNasWo.W W
