4) According to the Boeing Commercial Aircraft Company, a Boeing 747-400 aircraft has a maximum gross take-off weight of nearly 400,000 kg. Four pressure sensors are used to verify the weight reading found from suspension systems of Boeing aircraft. Each pressure sensor output is calibrated to produce 10 for 1 Kg of weight. Design a circuit using op amp, which add the four voltage levels from the four pressure sensors and check whether the sum exceeds the maximum take-off weight. If the maximum allowed weight exceeds, the circuit should give an indication by a buzzer and blinking a Red LED.

[Note: This is Lab based question. You are expected to draw the circuit diagram, do design calculations and perform simulation using Multisim or Tinkercad for verifying the results.]
