I have a beam secured by bolt (tighten) to the floor. the floor is assumed rigid. So which FBD is correct? (A), (B) or neither.
the bolt is secured in vertical position. So the beam can't rotate.
*note: I'm purposely not placing the reaction force, just need to make sure the type of support is correct first.
This is not exam question. This is for application to find tension force for the bolt to withstand
