1.The 60mm diameter shaft ABC is supported by two journal bearings, while the 80mm diameter shaft EH is fixed at E and supported by a journal bearing at H. If T1= 2 kN*m and T2= 4 kN*m, determine the angle of twist of gears A and C. The shafts are made of A-36 steel.
2.You have two containers, one of which contain 9 liters of liquid when filled to a mark and the other of which will contain 4 liters when filled to a similar mark.
