Solve for unknown

53 Views Asked by At

Hello Math stackexchange users!

This is my first question on math stackexchange. So if you have feedback for the question would be nice.

I am trying to solve the following

$$-\frac{M_A}{F} k \tan⁡\left(\frac{k(L_A+2L_B )}{2}\right)=\sin\left(\frac{L_B}{r}\right) $$

$$L_B =\ ?$$

Where all other variables are real and positive.

Is it possible to solve this analytically?
