G bone is an anisotropic tissue that supports higher loads in the longitudinal direction, due to the high level of organization of collagen and hydroxyapatite. the elastic modulus of a femur was found to be 40 gpa when measured in the longitudinal direction, and can be modeled as a composite with continuous oriented fibers. the volume fraction of the hydroxyapatite inclusions is 50%. the moduli of the inclusions and matrix are 79 gpa and 1 gpa respectively. the femur has a radius of 3 cm. determine the necessary radius of bone with entirely isotropic mechanical properties (i. e. inclusions are random particles now). in both cases, bone should not exceed a strain of 1%

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.
