For this problem, you will use Matlab to calculate the response of a locomotive and determining the maximum displacement. The locomotive has a mass of 2000 kg is is traveling at 10 m/s when it makes contact with a bumper. The bumper has a spring rate of 80 kN/m and a damping coefficient of 40 kNs/m. Write a Matlab script to calculate the natural frequency and damping ratio. Using these values, determine if the system is overdamped, underdamped or critically damped. Plot the response of the system using the appropriate response equation from the slides. Publish your Matlab script and upload it.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
