Let spring K1 be system A and spring K2 with damper be system B.
From spring properties, we know that
Substituting eq(1) and eq(2)
Rearranging like items,
Multiplying both sides by K1,
When length is first stretched, K1takes a
Where D is the distensibility,
L is the length of the chamber.
If not, the approximation would be false.
Since the whole body is in static equilibrium, we know that =0, and using point
O as the center (because the two other unknown F n and Fs both pass this point):
We know that 2Wb/3=660(N)
a=3cm, b=9cm, c=27cm
Since the whole leg is in static equilibrium, we know that =0, and using point O
as the center:
We know that Wl=120*.07=8.4(kg)
Solving for Fp=316.26(kg
b) Since the tympanic membrane is connected to the oval window with a rigid rod, they act
together as a body; therefore, when the tympanic membrane is displaced 1m, the oval window
is displaced 1m, and when the tympanic membrane moves with velocity
