(Civil Rngineering, Concrete Reinforcement). Design a T-beam for the floor system shown below. The span is simple and is 4.0 m, the service
applied moments are:
Md (dsad load) = 270kN. m
Ml (live load) = 575kN. m.

fc = 21MPa
fy = 420MPa.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way

Condition monitoring is a major component of. (clo4) a)- predictive maintenance. b)-preventive maintenance c)-proactive maintenance d)-reactive maintenance.
