Calculate the bending stress in a 1 ¾ in. x 12 in. x 18 ft. microllam lvl beam under the following load conditions: a)-2500 lb concentrated load at center with the beam fixed at both ends. b)-70.0 lb/ft uniform load with the beam fixed at both ends. c)-is the calculated stress acceptable?

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.
