Suppose the beam is carrying a known shear load of RDRDR_D = 29 kNkN . In this particular situation, the resistance factor is ϕ=0.9ϕ=0.9 for the shear load, and the nominal shear stress is 204 MPaMPa . What is the magnitude of the maximum live load (in addition to RDRD) that can be supported in shear by this beam

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
