As we know that force F makes an angle of 60 degree with X axis
so the X component is given as
now we have
Similarly we know that force F makes an angle of 45 degree with Y axis
so the X component is given as
now we have
Now for the component along z axis we know that
now plug in all components
Answer:
wavelength = 0.968 m
frequency = 39.02 Hz
Explanation:
given data
mass = 0.0127 kg
force = 9.33 N
length = 1.93 m
to find out
wavelength and Frequency
solution
we know here linear density that is
linear density = .........1
linear density =
linear density = 6.5803 × kg/m
so
wavelength will be here
wavelength = ..............2
here n = 4 for forth harmonic
wavelength =
wavelength = 0.968 m
and
frequency will be for 4th normal mode of vibration is
frequency = ..........3
frequency =
frequency = 1.036269 × 37.654594
frequency = 39.02 Hz
