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.

723_determine the largest value.png

The ball of a trailer hitch is subjected to a force If failure occurs when the moment of about point A reaches determine the largest value F may have and α for which the moment about A is the largest. Note that the value F you determine must not produce a moment about A that exceeds for 11250 in.·lb for any possible value of α

F = lb

α = °
