Project: Student Engineer Needed: Houseplant Watering System Some universities give students the opportunity to solve real-world problems in the community. Northwestern University engineering
students assisted with the design of public charging stations for electric vehicles. Students can use their skills to solve big and small
problems using engineering principles and designs. You will solve the watering needs for plants inside a home. The homeowner will be
away for one month. You will write a problem statement, identify a series of solutions, and choose the best design for a home
watering system
Assignment Directions
The design should include a problem statement, sketches, alternatives, and a final product design including materials needed. Your
design should be a minimum of five pages in length.

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.
