A simply supported beam 4.5m span carry a udl of 30kn/m including of self weight . The width of beam 230 mm and reinforced on tension side only design smallest concrete section. Use M 20 and Fe 250 reinforcement Assume load factor according to IS 456 2000.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?

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?
