Dynamics Problem
Question Figure shows a simple model of spring-mass system. The mass is released from the rest with the springs un-stretched. It’s downward acceleration is a=9.81 – 15.24y m/s2 where y is the position of the mass measured from the original position where it was released. (a) Calculate: i. The maximum y it falls. ii. What is the maximum velocity it reached during the fall? (b) ...more»

Get to know the cycloid!
In this article, we’ll talk about a very interesting curve: the cycloid. A point on the rim of a rolling disc traces out a cycloid. Here’s a nice animation that illustrates the concept - play around with it for a while. Lets discuss the mathematics of the cycloid in more detail - and see what its equation is. Consider the following ...more»
