Conservative Force ......ANSWER........A force, such as gravity,
that performs work over a distance that is independent of the
path taken.
What does a damper resist? ......ANSWER........What does a
damper resist?
What does a spring resist? ......ANSWER........Displacement
Parallel Axis Theorem ......ANSWER........I = Icm + md^2
,age 2 of 19
When can gravity be ignored in a vertical mass-spring-damper
system? ......ANSWER........When the displacement is defined at
equilbrium
kinetic energy formula mechanical
......ANSWER........KE=1/2mv^2
The equivalent spring constant of two springs in parallel?
......ANSWER........kt = k1 + k2
The equivalent spring constant of two springs in series is?
......ANSWER........kt = 1/k1 + 1/k2
kinetic energy rotational ......ANSWER........KE = ½Iω^2
The sum of the kinetic and potential is constant when?
......ANSWER........Forces considered are only conservative
, age 3 of 19
If a system has both translational and rotational elements
......ANSWER........concept of kinetic energy to convert to purely
translational or rotational
Op Amps Golden rules ......ANSWER........1. input terminals have
no current ( i1 = i2 = 0)
2. op amp will try to maintain zero differential input voltage (vin
= 0)
commutator ......ANSWER........A device that controls the direction
of the flow of current through an electric motor so force is
always in same direction
Back EMF ......ANSWER........The emf induced in the spinning coil
of electric motor or in any coil in which the current is changing.
