This is not a homework problem rather it is a discussion that I have been having with friends. *Your thoughts and feedback would be appreciated.
Blocks A and B are on a horizontal surface and connected to one another by a load cell.
Block A has mass m1 and Block B has mass m2.
Each block has difference coeff of static and dynamic friction.
Load cells are connected to the left and right of the blocks.
A right horizontal force F1 is applied to the*
All blocks accelerate at the same rate.
The applied force is much greater than the frictional force.
Diagram
-(#)- = load cell
-(1)-A-(2)-B-(3)-
Questions.
1) What are the forces at each load cell.
2) Assume that the system eventually hits a wall but F continues to be applied. *What are the forces a each load cell after impact.
-(1)-A-(2)-B-(3)-WALL
1)*
The force at location (1) is:
u1*N1+u2*N2
Where u represents friction coeff and N is normal force.
The force at location (2) is:
u2*N2
The force at location (3) is simply zero.
In the case where*
The force at location (2) is*
2)*
Once we hit the wall we have a change in the reactionary forces.
The reactionary forces cancel out and the force throughout the entire chain is F.
Position 1 is F, position 2 is F, position 3 is F.
