SECTION A

(Answer THREE questions from this Section)

1. SUSPENSION SYSTEM

📷 Note: Refer to Figure 1.1 in image_5ed201.jpg to view the independent front suspension layout, showing the coil spring assembly, control arms, and crossmember (labeled parts 1 through 7).

• (a) Referring to Figure 1.1, identify the numbered parts 2, 3, 4, 5, 6, and 7. (3 marks)

• (b) State the role of component 3 on vehicle body movements. (1 mark)

• (c) Give FOUR functions of component 4 of Figure 1.1 in the suspension system of a vehicle. (4 marks)

• (d) What effect would lowering the suspension system have on steering geometry? Justify your answer. (2 marks)

2. SUSPENSION SYSTEM DIAGNOSTICS & VARIATIONS

Figure 1.2 shows another type of suspension system configuration.

📷 Note: Refer to Figure 1.2 in image_5ed201.jpg to view the longitudinal/torsion bar type suspension schematic (labeled parts 1 through 9).

• (a) Identify the type of suspension shown in Figure 1.2. (1 mark)

• (b) Give THREE advantages of an independent front and rear suspension system. (1.5 marks)

• (d) Give TWO possible causes each for the following suspension system problems (faults): (3 marks total)

  • (i) Excessive pitching. (0.75mark x 2 = 1.5marks)

  • (ii) Hard ride. (0.75mark x 2 = 1.5marks)

• (a) Give ONE symptom of a worn suspension rubber bushing. (1 mark) (Note: The page restarts lettering at ‘a’ and ‘b’ for these final troubleshooting questions).

• (b) State ONE possible cause each for vehicle instability when: (2 marks total)

  • (i) Cornering. (1 mark)

  • (ii) Driving on rough and uneven road surfaces. (1 mark)

Tips for WordPress Optimization:

• Image Delivery: Crop Figure 1.1 and Figure 1.2 from image_5ed201.jpg and embed them directly above their respective question sections so students can match the numbered components easily.

• Typos Fixed: Automatically corrected the typo in the original heading from “SUSPENSION SYTEM” to SUSPENSION SYSTEM for better SEO.

• Categories: Vehicle Dynamics, Suspension Systems, Automotive Troubleshooting.
