Consider an orthotropic e-glass /epoxy composite cube of dimensions 100 mm x 100 mm x100 mm. The cube is subjected to an extension in the 2 direction of 0.7mm and is constrained against contraction in the 3 direction. Calculate the stress and strains in all the principal directions. E1

An industrial centrifugal air compressor has 34 radial blades that has no pre-whirl. the tip speed of the blades is 300 m/s, and the radial component of the air velocity at the tip is 150 m/s. air is inducted at 101.3 kpa and a stagnation temperature of 305 k. the mass flow rate is 3 kg/s. consider the power input factor to be equal to 1.04 and a stagnation temperature at the compressor exit of 370 k, if the flow is isentropic. assume cp-1005 j/kg.k. find the power input to the compressor (in kw)
