Homework: A helica) cast steel with 30 helix angle has to tanmit 35 KW at 15oo yon. Gear has 24 teeth , 20 full depth. The Static Stress for Cast Steel maybe taken as 56 Mpa. The width.of face may be talcen as 8 times th module. Assume: Cs =l, Ep=E,=200GPa Ges=B00 MPa, be =60 MPa, Calculate: WA, WN,m, b, VR, C=40.

A steel cantilever beam is fabricated from two structural tees welded together, as shown in the figure. For this beam, the allowable bending stress is 150 MPa, the allowable shear stress of the steel is 100 MPa, and the allowable shear flow along the weld is 2MN/m. Determine the allowable force P that the beam can carry. (All dimensions are in mm).
