The last one:
This is straightforward to show that there's no exist δ λ such that:
-24.7= sin(2*δ)*sin(λ)*19.817
(this can be true only if δ λ are complex)
Do you mean that the force of spring should looks like this:
Fs=-k(x-Asin(wt))
and now the differential equation will be:
M_{1}\frac{d^{2}x}{dt^{2}}+b\frac{dx}{dt}+kx=k*Asin( \omega t)
Now the differential is dimensionally consistent.But, is that correct??

tring constant is k,
object mass is M_{1}
Damping friction is b
and we wiggle the top end of spring in the above diagram with amount Asin(wt)
(Where A is a amplitude and w is a frequency).
