Show your work (you need to support your answers, right or wrong, with the work that leads to those answers). Each
problem is equally weighted in the overall exam grade.
A support bracket for the mower deck of a lawn tractor is shown below where F1 is horizontal. Determine the
magnitude of F2 so that the resultant of these two forces is vertical. Determine the magnitude of the resultant force.
