A) - Draw sketch for an estimated S-N diagram for a hot-rolled finish steel bar (AISI - 1060) and define its equations.
b) - How many cycles of life can be expected if the completely reversed stress is 150
MPa?
c) - What is the applied reversed stress for 105
cycle life?
Given the value of = 0.4

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
