In an otherwise symmetrical portal frame with one end fixed and the other end hinged, the large support sinks by an amount Δ. The fixed and bending moment induced at each end of the horizontal member of the frame due to the sinking of the support will be (given that 'L' is the length of the member and 'E' is the flexural stiffness)

The total observed runoff volume during a 4 hour storm with a uniform intensity of 2.8 cm/hr is 25.2 x 10^{6} m^{3} from a basin of 280 km^{2} area. What is the average infiltration rate for the basin ?

A car accelerates from rest to a speed of 10 m/s and the energy spent in doing this is E. If the car is further accelerated from 10 m/s to 20m/s, what is the amount of energy to be spent further ?
