1. The problem statement, all variables and given/known data
A heavy weight is suspended by a cable and pulled to one side by a force F. How much force is required to hold the weight in equilibrium at a given distance x to one side. Tcosθ=W and Tsinθ=F. Find F/W as a power series of θ. Often in a problem like this, what we know is not θ, but x and l. Find F/W as a series of powers in x/l.
l is the length if the cable
W is weight
T is the tension in the cable
2. Relevant equations
3. The attempt at a solution
