Design a steel hollow column of length 15-m with minimum weight for a water tank such that it can carry a water tank of 45000 kg. The tank is to designed such that to withstand a ground vibration due to an earthquake. The earthquake excitation is idealized as undergoing a harmonic ground acceleration of amplitude of 0.5 g. The natural frequency of the water tank should exceed 20 Hz. Assume the Yield Strength for the steel to be 250 MPa. Assume a damping ratio of 5 = 0.2.

A 20-Mg train is traveling at a speed of 50 m/s. But the driver noticed that the bridge 300-m ahead is missing. At once, he pulls the break, thus applying a frictional resistance of Ff = 1000 N. At the same time Super Botting pushes back the train with a force of Fs = [800d+100] N, where d is the distance that the train travels before stopping. Determine the stopping distance d, and mention whether or not Super Botting would be able to save the train. ps. Don't copy the other answer. He/she/they didn't not consider the angle 10 degree.
