Determine the moment M that should be applied to the beam in order to create a compressive stress at point D of . Also sketch the stress distribution acting over the cross section and calculate the maximum stress developed in the beam.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis
