Scenario 1 Your boss, Melon Usk, wants you to determine the acceleration of his new car. The details of the car are as follows: The car's total mass is 1500 kg The motor outputs a constant torque of 300 Nm The drive train has a gear ratio of 10:1 to the drive axle Prior to any gearing, the motor and drivetrain have a moment of inertia of 0.5 kg m². The four tires are 0.6 m in diameter. A single set of final gear, drive axial, and tire has combined moment of inertia of 0.6 kg m². Not knowing how to proceed, you e-mail your favourite ex-instructor, Frank. He is very busy but draws you the following: ● ● ● ● ● ● Motor ● FT+ IM = 0.5 kg. m² TIN = 300Nm TIN Final Gear + Wheel Wheel RG Final Gear C Rw Fw Iw = 4(0.6 kg m²) = 2.4kg. m² RG = 10R Rw = 0.3m Car Fw m = 1500kg y x Frank also notes the following: You can treat all four tires, axels, and final gears as a single entity. The moments of inertia will add together but the radius will remain the same. You do not need to know the complex…

You’re testing a system that involves a fan, water pump, and compressor. The components are turned ON in sequence and sensor readings are taken, as per a written protocol that you’re following. The system is running as expected after the fan and water pump are turned ON. However, when you turn ON the compressor, it runs for about thirty seconds then stops, consistently. Swapping out the compressor for a different one seems to solve the problem. What could have been the issue with the bad compressor?

After some engine model replacement, an aircraft model is experiencing some aggressive nose up phenomenon which may lead to stall. To combat this problem, a new control system has been introduced to the Flight Control Computer, FCC. When activated, the new system measure the aircraft pitch from an Angle of Attack, AOA sensor to analyze either the aircraft is nosing up or down. If the pitch angle is too high, describing that the aircraft might be in a dangerously nose up position, the FCC will gain control of the horizontal stabilizer using a linear motor (FIG 1), thus bringing the nose of the aircraft down into safer pitch angle range (FIG 2). a. What is the input/output of the control system? b. Is this system is a close loop or open loop? c. What is the actuator used in this control system? d. Draw the Block Diagram to describe the control system. Horizontal stabilizer Pivot Horizontal stabilizer 000000c Jackscrew moves the angle of the horizontal stabilizer up or down. Motor Figure…

Answer the following questions, to test your understanding of sampling frequency and bit depth. 1. You are part of new automobile design team, and are responsible for designing the sensor data collection system. The specification of the data collection system is that is must be capable of receiving data with a resolution down to 0.1% of full scale (1 part in 1000) for any given sensor. For example, suppose the driver pushes the gas pedal, the motion of which is read by an electronic sensor such that the range of motion is defined from 0 (not pressed) to 1 (fully pressed). If you want 0.1 % accuracy, you need 1000 possible data values between 0 and 1. How many bits do you need to represent data to 0.1% accuracy? Insert a picture of your work.

A completely automated Tesla travels up a 3% incline at 30 mph on a road that has good, wet pavement. The car has a wheelbase of 120 inches and a center of gravity that is 55 inches behind the front axle and at a height of 20 inches. The braking efficiency is 88%. It notices a pothole 35 ft ahead of the car and comes to a complete stop.   a) Calculate the percentages of braking force that should be allocated to the front and rear brakes to ensure that maximum braking forces are developed.   b) Will the car hit the pothole if it has (i) no antilock brakes and (ii) antilock brakes (braking efficiency 100%)?   Assume theoretical stopping distance and neglect aerodynamic resistance.

A hotel chain based in the United States contracts with a European vacuum cleaner manufacturer to supply a large number of upright cleaner units. After delivery, the hotel raises questions about manufacturer vacuum cleaner performance claims, pointing out that the units should have been tested to meet ASTM 558, an American standard. The manufacturer notes the advertised performance is based on IEC 60312, a European standard, and the two test codes will yield similar, if not exact, results. Investigate both test codes and address similarities and differences. Is there a legitimate claim here?
