Textbook Question
Chapter 19, Problem 10RQ
For the protection of both the operator of a zero-turn radius mower and the mower itself, several safety interlocks must be implemented. These interlocks and the variables that will represent them are listed shown here:
Interlock Description | Variable Used | State |
Brake switch | Brake | True if brake on |
Operator seat switch | Seat | True if operator seated |
Blade power switch | Bladco | True if blades turning |
Left guide bar neutral switch | LeftNeutral | True if in neutral |
Right guide bar neutral switch | RightNeutral | True if in neutral |
lanolin switch | Ignition | True if in run position |
Motor power interlock | Mot or | True if motor enabled |
For the motor to be enabled (thus capable of running), all the following conditions must be true.
- The ignition switch must be set to Run.
- If the operator is not properly seated, both guide levers must be in the neutral position.
- If either guide lever is not in the neutral position, the brake must be off.
- If the blades are powered, the operator must be properly seated.
Write a function that will accept all of the preceding variables except Mot or, decide whether the motor should be enabled or not, and place true or false in Motor as the returned variable.
