CHAPTER 11 : Equilibrium and Elasticity
The Conditions for Equilibrium
Torque,τ net=o
Fnet=0
Solving Statics Problems
Force negative means opposite direction
Stability and Balance
stable equilibrium = return to a desired position or trajectory following a disturbance
at tipped= unstable
Elasticity; Stress and strain
Hooke's law, F = kx
Young Modulus(N/m^2)
Shear Modulus
Bulk Modulus
Fracture
a things will fracture if stress too big
Trusses and Bridges
Arches and Domes
The steeper the arch, the less the horizontal component of the force needed
