The input shaft of a speed reducer supports a 200 N·m moment, and the output shafts support 300 and 500N·m moments.

(a) Determine the resultant moment applied by the shafts to the speed reducer.

(b) If the speed reducer is bolted to a surface that lies in the xy plane, speculate on the characteristics of the forces these bolts apply to the speed reducer. In other words, do you expect these forces to constitute couples only, or may they be more general?

Remark: Problems such as this are discussed in detail in Chapter 5.
