The hinge between the two members of the following beam is replaced with a rational spring with a stiffness �" = ��/� , where � = 20 ft = 240 in . 1) Use hand calculation to determine the joint displacements, member forces and support reactions; 2) Re-do the problem using computer program for the hinge connection; 3) Re-do the problem using computer program for the rigid connection; 4) Discuss the results.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Avolume of 2.65 m3 of air in a rigid, insulated container fitted with a paddle wheel is initially at 264 k, 5.6 bar. the air receives 432 kj by work from the paddle wheel. assuming the ideal gas model with cv = 0.71 kj/kg • k, determine for the air the amount of entropy produced, in kj/k
