In this article, (and video above), we calculate the compression of a loaded spring to give you a better understanding of what you can expect during the exam. This week’s problem was created and solved by Enrique Ivers, an Engineer in Training.
Question:
A disk with a mass of 1kg, a diameter of 10cm, and a width of 5cm is placed on the edge at the top of an inclined ramp 1m high. The ramp is inclined at 15°. At the bottom of the ramp is a spring whose spring constant is 2,000 N/m. The disk rolls down the ramp and compresses the spring while coming to a complete stop. What is the maximum compression of the loaded spring?
