A mechanics problem has led me to the following but I have to rearrange in order to find a solution in terms of P.
Pcos20=µ(30g-Psin20)
Where µ=0.4 and g=9.8
How do I go about rearranging this? I have been trying for hours and many screwed up pages later I am no closer to making the connection. It is probably really simple.
Thanks guys.
