                          5  Power is to be transmitted from an electric motor to a conveyor through a belt drive
                             and a two-stage gear reducer. A pair of spur gears and a pair of helical gears are to
                             be used in the gear reducer. Propose at least two designs and compare them.

                          CAD Problems

                          1  Write a flow chart for the gear drive design process.

                          2  Develop a program to implement a user interface similar to Figure P8.5 and complete
                             Example Problem 8.1.
