Remember that a pin support has two reaction forces ( ), while a roller only has one ( Nycap N sub y
Remember that in this course, nothing bends. If it’s supposed to bend, you’re in the wrong class (that’s Strength of Materials!). Vector Mechanics for Engineers
Are you currently working through a specific chapter, like or Rigid Body Rotation , that we could break down further? Remember that a pin support has two reaction
This is just geometry and time. Position ( ), velocity ( ), and acceleration ( This is just geometry and time
You’ve heard it a thousand times, but it bears repeating:
If the problem asks for velocity at a specific , use Impulse-Momentum . 5. Pro-Tips for Success
Here is a quick guide to surviving and thriving in your Vector Mechanics course. 1. The "Golden Rule" of Statics: The FBD
