Determine the force in each member of the truss (ab, bd,

ac, bc, cd, de, df, eg, ef, gf) and state if the members are in

tensionor compression. set p1 = 2 kn. p2 = 4 kn. at every letter

there isa pin connection.

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.
