Question (i)
Describe two factors to be considered when selecting appropriate materials for the electric-powered Formula E car shown.
Worked Solution & Example Answer:Describe two factors to be considered when selecting appropriate materials for the electric-powered Formula E car shown. - Leaving Cert Engineering - Question (i) - 2020
Step 1
Factor 1: Lightweight Robust Materials
Answer
The Formula E car is battery-powered, making it vital for the materials to be lightweight yet robust. This helps minimize the overall weight of the car, allowing the battery to operate more efficiently. Lighter materials reduce the energy required to move the vehicle, leading to enhanced battery performance.
Step 2
Factor 2: Strength-to-Weight Ratio
Answer
The strength-to-weight ratio of the chosen materials is crucial. A high-strength material that is also lightweight will ensure the car can withstand impacts and stress during high-speed racing. This not only improves safety but also allows the car to perform better at higher speeds, as the battery has less work to do.
