(a) Find the magnitude of the moment about $$O$$ by evaluating $$?\overrightarrow{OA}\times \mathbf{F}??\left(0???180^{?}\right)$$ Use a graphing utility to graph the resulting function of $$?$$. (b)..use.the.result of part (a) to determine the magnitude of the moment when $$?=45^{?}$$. (Round your answer to two decimal places.) $$i^2$$ (c) Use the result of part (a) to determine the angle $$?$$ when the magnitude of the moment is maximum.
