1.A thin film of oil (v=0.001 m^2/s) 2mmthick flows down to a surface inclined at 30 degrees to thehorizontal. What is the maximum and mean velocity of flow?

2.Whisker filaments of SiC that are 5 μm thick are coated withan aluminum alloy using a chemical bonding process. The coating process is carried out at 650 oC before the sample iscooled to room temperature. Elastic stresses due to thermalexpansion mismatch do not begin to appreciably accumulate until thealloy has cooled to approximately 200 oC due to alloyviscosity. If the stresses necessary to maintain whisker/coatingcompatibility are assumed to be normal stresses acting only in thedirection of the filament axis, what is their sign and magnitude at20 oC? Relevant materials properties are:ESiC = 476 GPA, EAl = 70 GPA,αSiC = 4.7 x 10-6/oC,αAl = 21 x 10-6/oC.Looking a wood (pine) deck material. It's a simple 8' by 8' deck. There's a support beam holding up this deck. Other end is connected to building. I'm trying to find the load bearing strength of a support beam -- in lbs, that supports this deck under it. Average usage of deck or persons on it. Anyways, what is the strength of a single 8 foot 2" by 12" beam? Then what is the strength of a single 8 foot 2" by 10" beam?

3.102 Determine the intensity w of the maximum distributed load that can be supported by the hanger assembly so that an allowable shear stress of τallow = 13.5 ksi is not exceeded in the 0.40-in.-diameter bolts at A and B, and an allowable tensile stress of σallow = 22 ksi is not exceeded in the 0.5-in.-diameter rod AB.
