Physics 1301A/B Lecture 12: Chapter #12: Static Equilibrium

hi,

What is the centre of gravity? Explain with example.

for an object to be in static equilibrium, the net force must be equal to zero, and

a)The net torque must be equal to zero.

b)The normal force must equal the weight.

c)The moment of inertia must be zero.

d)The center of gravity must be above the support point.
