Answer:
Diagram B because a plate resting on a table has gravity acting on it and normal/air resistance force working against the gravity with the same amount of force. Forces that are balanced don't move.
Explanation:
I hope this helps
pivot = 8 in
Balance lenght = 27 in - 8 in = 19 in
Load x load arm = Force x force arm
Replacing:
600 lb * 8 in = F * 19
Solve for F
F = 600 * 8 / 19
F= 252.6 lb
The answer is D. 1
Hope I helped!
