Question 8
HLPaper 2
A company is designing a height-adjustable standing fan for home and office use. They want to ensure users can easily control the fan's direction, height, and speed using simple mechanical systems. The design must be cost-effective, user-friendly, and reliable.
1.[1]
Figure 1: A standing fan with a telescopic pole and height-adjustment
i.) Identify the type of motion created when adjusting the height of the fan.
2.[1]
ii.) State one reason why telescopic poles are used in height adjustment.
3.[2]
Figure 2: Close-up of the fan’s oscillation mechanism using a crank and gear system
i.) Outline how the crank and gear mechanism produces oscillating motion.
4.[2]
ii.) Describe one benefit and one drawback of using this mechanical oscillation system.
5.[3]
Figure 3: Control panel showing a rotary dial for adjusting fan speed
i.) Explain two advantages of using a rotary dial over a digital button interface.
6.[6]
ii.) Discuss how using mechanical systems in this fan supports sustainable design.
Question 9
HLPaper 2
1.[9]
Compare the three types of levers and their use in mechanical systems.
Question 10
HLPaper 2
1.[2]
Identify two components in a mechanical system that convert input into output.
