A force of F = 90 N acts on the handle of the paper cutter at A as shown in (Figure 1).
Part A
If θ = 60∘ determine the moment created by this force about the hinge at O Express your answer to three significant figures and include the appropriate units. Assume the positive direction is counterclockwise.
Part B
At what angle θ
should the force be applied so that the moment it creates about point O
is a maximum (clockwise)?
Express your answer in degrees to three significant figures.
Part C
What is the magnitude of this maximum moment?
Express your answer to three significant figures and include the appropriate units.
