The star system 40 Eridani is composed of three stars (labelled simply A, B, and C) in orbit around each other. 40 Eridani A is a main-sequence dwarf, with B a white dwarf and C a red dwarf. We will treat them as spherical blackbodies.

find an expression for the temperature of each of the stars of the have the following

A: energy density Mla and a wavelenght la
B: energy density Mlb and a wavelenght lb
C: energy density Mlc and a wavelenght lc

where the energy density follows plancks law, would the temperatures differs if e the emissitivity would be less than 1? (i.e not a perfec blackbody)

Ml = cU/4V

You are analyzing a 40 FT long simply supported beam (b = 10 IN, d = 21.5 IN, h = 24 IN) in an existing building. The dead load on this beam is 1.2 KLF and you are tasked with deciding whether a load of 2 KLF of live load can be applied in addition. Based on the original plans, you think that the compressive strength of the concrete f’c = 3000 PSI and the yield strength of the rebar...
