Given a digital filter with the following numerator and denominator coefficient vectors, respec-
tively:
num= 0.8831, 1.6234, 2.5118, 1.6234, 0.8831, and
den= 1., 1.7342, 2.5277, 1.5502, 0.7998.
find the poles and zeros of the filter transfer function. is the filter stable?
plot the magnitude and phase of h(ejω) of the filter. hence, determine the type of filter
(lp, hp, bp, or notch) it represents.
determine the 3-db bandwidth of the filter.
if the sampling period is t = 10 µsec, determine the 3-db bandwidth in hz.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

c) up

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
