PHYS 200 Unit 9: Statics and Torque
Flashcards do conjunto (11)
- 1static equilibrium-state of equilibrium in which net external force and torque is 0
-acceleration of system is 0 and accelerated rotation does not occur - 2dynamic equilibrium-state of equilibrium in which net external force and torque on system moving with constant velocity are 0
- 3torque-turning/twisting effectiveness of force rotational equivalent of force
-measure of effectiveness of force in changing/accelerating rotation - 4perpendicular lever arm-shortest distance from pivot point to line along which F lies
-r_τ = rsinθ - 5formula for torque-τ = rF┴
-τ = r(Fsinθ)
-τ = F(rsinθ)
-τ = Fr┴ - 6conditions to achieve equilibrium--net F_x = 0
-net F_y = 0
-net τ = 0 - 7stable equilibrium-displaced system that experiences net force or torque in direction opposite to direction of displacement
- 8unstable equilibrium-displaced system that experiences net force or torque in same direction as displacement from equilibrium
- 9neutral equilibrium-state of equilibrium that is independent of system's displacements from original position
- 10simple machine: lever-type nail puller(l_i)(F_i) = (l_0)(F_0)
- 11mechanical advantage-MA = (F_0) / (F_i)
-MA = (l_i) / (l_0)
