At what angle © must the 400-1b force be applied in order that the resultant R of the two forces have a magnitude of 1000 lb? For this condition what will be the angle B between R and the horizontal?

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?

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