Create a chart block for defining the stateflow as per the given conditions.

Inside it, the circular junction is to terminate the signal flow and return a null value.

If power is OFF i.e. 0, the process is terminated at the junction else 1 is carry forwarded. If water is OFF i.e. 0, the process is terminated at the junction else 1 is carry forwarded. After this, at 200 sec Soak block gets activated and soaking action takes place.

After 300 sec of Soaking, Wash block gets activated and washing action takes place. After 320 sec of Washing, Rinse block & gets activated and rinsing action takes place. After 370 sec of Rinsing, Dry block gets activated and drying action takes place.

After then the signal flow in the process and exits the chart.

Define power and water as inputs whereas soak, wash, rinse, dry, finish as outputs.

Connect the chart block with; constant blocks for power and water inputs. Input switches connected to them are slider switch and a toggle switch respectively (to distinguish between the two). Attach lamps to observe the ON/OFF condition.

A common scope block is connected to observe the entire washing process and obtain the output plot. Blue colour in the lamp indicates that the process is complete.

GEAR SHIFT

A manual transmission also known as a manual gearbox a standard transmission or colloquially in some countries as a stick shift is a type of transmission used in motor vehicle applications. It uses driver operated clutch, usually engaged or disengaged by a foot pedal or hand lever for regulating torque transfer from the engine to the transmission and the gear selector can be operated by hand.

A conventional 4 or 5 speed manual transmission is often the standard equipment in a modern based model vehicle with 4 speed being more common in non-passenger vehicles such as pickup trucks and light commercial vehicle & higher end vehicles such as sport cars and luxury cars are often ususally equipped with 6 speed transmission for base model.

Gearbox is the second element in the powertrain in an automobile. It is used to change the speed and torque of vehicles according to the variety of road and load conditions. The transmission box changes the engine speed into torque when climbing heels and as per requirement of the vehicle & hence it is also known as torque converter.

Following are the functions of the gearbox-

1. Provide the torque needed to move the vehicle under the variety of road and load conditions and doing this by changing the gear ratio between engine crankshaft and vehicle drive
2. To provide assistance to shift backwards/ reverse so that vehicle moves in that
3. To help the vehicle to shift into neutral for starting the

Working – In a gearbox the tertiary counter shaft counter shaft is mashed to the clutch with the use of couple of gears so the countershaft is always in running condition. When the tertiary shaft is brought in contact with the main shaft by the use of meshing gears the main shaft starts to rotate according to the gear ratio. When thhe driver wants to change the gear he simply press the clutch pedal which disconnects the tertiary shaft with the engine and connects the main shaft with the tertiary shaft by another gear ratio by the use of gearshift lever.

conclusion: Hence, the given problem was simulated for the washing machine and gear shift mechanism and executing the Stateflow as per according to given conditions
