Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

Q4.) The 12 kg block A and 10 kg block B are pinned to a rod having negligible mass and resting
on horizontal surfaces. A horizontal force P is applied to the rod at end C increasing gradually
from zero until motion first begins.
a) If the coefficient of static friction between both blocks and each surface is μ = 0.45,
determine the value for P at which point motion first begins and describe the motion that
occurs in a few brief words.
b) If the coefficient of static friction between both blocks and each surface is μ = 0.6,
determine the value for P at which point motion first begins and describe the motion that
occurs in a few brief words.
(Hint: Consider drawing the system as one FBD for this analysis and treat each block as a
particle with negligible dimensions)
