Figure Q5(a) shows a continuous reinforced concrete beam of three equal spans 8 meach. The beam carries uniformly distributed load over its entire span which consists ofcharacteristic dead load (including self-weight) of 25.0 kN/m and characteristic imposedload of 10.0 kN/m. The beam cross section with the designed reinforcement is shown inFigure Q5(b). The construction materials used in the design are Grade C35 concrete andGrade 500 steel reinforcement. The nominal concrete cover to links is 30 mm, while theelastic modulus of concrete and steel are 33 kN/mm2and 200 kN/mm2respectively. Theestimated creep coefficient is 2.3 and the final shrinkage strain is 280 x10-6.Calculate the long term deflection of the beam at mid span A-B at serviceability limitstates.
A uniform rod is rotating on a horizontal plane about a vertical axis through one end with a constant angular velocity ω0. Due to internal shear forces, the rod breaks at the mid-point of its length, and the part with the fixed axis has an angular velocity 1.5ω0 in the same sense. Determine the angular velocity of the other half.
Consider the following statements and mark the statement as you answer which is correct in the context of kinetic energy and potential energy.
The kinetic energy of a molecule depends on the temperature while potential energy depends upon the position
The kinetic energy of an object is due to its position while potential energy is due to its velocity
Both kinetic and potential energy of an object can be maximum at the same time
None of these
