The Shaft Shown is ma de from steel Pipe branze core. 1ut side radius = 30 mm inside Radins- 15 Mm a) Fird the Maximum shear Stress in both materials bi) Determine the rotation of point A in degree

Please Help ASAP!!!

The two solid shafts are connected by the gears shown. The motor constantly supplies 20 kW of power at 15 Hz to system at A. The yield shear stress is 140 MPa for shaft (1) and 220 MPa for the shaft (2), and over all factor of safety is 2. a) Find the diameter of both shafts. b) If the modulus of rigidity of shaft (2) G is 77.2 GPa, calculate the relative angle of twist D with respect to C. 30 teeth B (1) 48 teeth Tp 0.8 m

The 54-mm-diameter solid shaft is subjected to the distributed and concentrated torsional loadings A) Specify the location of the absolute minimum shear stress on the outer surface of the shaft, measured from the fixed end A. Express your answer to three significant figures and include the appropriate units. B) Specify the location of the absolute maximum shear stress on the outer surface of the shaft, measured from the fixed end A. Express your answer to three significant figures and include the appropriate units.
