This blog today is going to be from in class, about mechanical movement cranks and cams. Wheels and axles are attached, the wheel is a larger cylinder than the axle. Works like a lever. Center point to the edge of the axle is radius, and the center point to the edge of the axle to the wheel, and you can calculate the mechanical advantage. Now I am going to be talking about the cams. Followers can come in multiple shapes, but we are using flat followers. In the bearing, the rod goes up and down. While building cams, you have to figure out if our followers move enough. To find this out you can measure the axle with the closest point and the furthest point. Subtract, and that is how far it would travel. Cams can come in any type of shape.
