Undergrad Where is a contact force labeled on a diagram of a pivoted beam?

Click For Summary
A contact force, such as friction, normal force, or tension, is exerted by one object on another through direct contact. In diagrams of a pivoted beam, these forces are represented by arrows originating at the point of contact. The direction and size of the arrow reflect the specific details of the situation. Labels for the forces are typically placed near the tip of the arrow for clarity. This explanation clarifies how contact forces are depicted in relevant diagrams.

Hi...What is a contact force and where is it labelled in a diagram showing a beam pivoted?
 
Physics news on Phys.org
A contact force is something like friction, normal force, tension that are exerted by one object on another through contact. It is drawn as an arrow with its tail at the point where the contact is made. The direction and the size of the arrow depend on the details of the situation. The label usually appears somewhere near the tip of the arrow. Does that answer your question?
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
