The steel pipe ab has a 102-mm outer diameter and a 6-mm wall thickness. knowing that arm cd is rigidly attached to the pipe, determine the principal stresses and the maximum shearing stress magnitude at point k. (round the final answers to one decimal place.) given: f = 10 kn

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
