A 2 by 4 wood beam (E = 2000 ksi) with an allowable flexural stress of 1200 psi is subjected to bending around it's strong axis. Determine the % increase in flexural moment capacity if the beam is reinforced by 2 0.25" steel (E = 30000 ksi) plates with an allowable flexural stress of 24000 psi at the top and the bottom of the beam respectively.

a) What is the minimum index of refraction of a clear material if a minimum thickness of 122 nm , when laid on glass, is needed to reduce reflection to nearly zero when light of 675 nm is incident normally upon it? Assume that the film has an index less than that of the glass. I got nmin=2.76 and it is saying incorrect.. used the equation 2t=m λn not sure what I am doing wrong b) What is the main...
