Mechanical Advantage and Wedge Systems

The video tutorial explores the concept of mating wedges, focusing on a 30-degree wedge and a 60-degree wedge. It explains how to calculate the x and y displacements using trigonometry, specifically the tangent function. The tutorial also covers how to determine the mechanical advantage of the wedge system, highlighting that the output force is greater than the input force, assuming no friction losses. The video concludes with a call to action for viewers to engage with the content.

What is the primary goal when analyzing the mating wedges in this problem?
