Find the moments of inertia Ix, Iy, I0 for a sheet that occupies the region D and that has the given density function.. D = {(x, y) | 1 ≤ x ≤ 3, 1 ≤ y ≤ 4}; (x, y) = ky2

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

Aquick transition of the operating speed of a shaft from its critical speed will whirl amplitude. (a) increase (b) limit (c) not affect (d) zero

Air flows over a heated plate àt a velocity of 50m/s. the local skin factor coefficient at a point on a plate is 0.004. estimate the local heat transfer coefficient at this point.the following property data for air are given: density = 0.88kg/m3 , viscosity 2.286 x 10 ^-5 kgm/s , k = 0.035w/mk ,cp = 1.001kj/kgk. use colburn reynolds analogy.
