Consider a fully upright pencil.
True or False: A balanced pencil on its tip is an example of stable equilibrium.
Visualize what happens with even a small push.
A bar with a spring is held at an angle of 10 degrees to the vertical. Calculate whether the situation is stable or unstable when subjected to a load of 50 N.
Consider the angle's effect on moment calculations.
