Determine the period of oscillations in trial i. we recommend starting at the equilibrium position. even though the video is shot at 30 frames per second, it may be challenging to find the frame where the "x" is exactly lined up with the equilibrium. do your best. did we mention that you need to find the period for trial i?

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.

What is a monomer? how do they form a ploymer from the view point of chemical bonding?

A)-in the process of engineering design, explain the contribution of material selection. b)- explain the procedure of synthesis as is employed in engineering design. c)- is there any relationship between ergonomics and engineering design? explain. d)- safety consideration in engineering design includes human, product and the enviroment . explain how safety will be incorporated into the design?
