Question

Part A
Learning Goat
To be able to caloulate couple moments
A couple is defined as two parallel forces, separated by a
distanco, that have equal magnitudes but opposite
directions. A couple orly produces a rotation in a spocifed
drection. The moment produced by a couple is called a
couple moment
As shown, a submanne hatch door is to be opened by applyiog two oppositely onented forces of equal magnitude
F-55.0lb at pointh A and Bon the halch door whoel. The radi of the wheol's inner and outer rings are ri200 ft and
n0 500 t. respectively. (Figure 1) Calculate the moments M and Afn about point Dfor the foroas applied at points A
and B. Then, delermine the resulting couple moment M. Assume nat a postive moment produces a counterdiockwise
rotaton whereas a neogative moment produces a docknise rotation.
Express your answers numerically in pound-feet to three significant figures separated by commas.
