Do not round intermediate calculations; however for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to three significant figures.
The ball of a trailer hitch is subjected to a force F. If failure occurs when the moment of F about point A reaches 11250 in.·lb, determine the largest value F may have and specify the value of α for which the moment about A is the largest.
Note that the value of F you determine must not produce a moment about A that exceeds 11250 in.·lb for any possible value of α.
F = lb
α = °
