intend to weld to the shaft of the gas turbine as shown in the figure. At a rotational speed of 26,00 rpm, 250 kW of power is transferred. Calculate the following (1) shear stress of the weld when the shaft diameter is 46 mm. However, the allowable shear stress of the base metal is 5 kgf/mm2, and the weld coefficient is 1. (2) Calculate the thickness a of the weld.
