Answer :
Final answer:
The brake drum in a cast spoke wheel assembly is mounted on the inboard side of the wheel hub, facilitating a compact design and aiding in heat dissipation. Therefore the correct answer is a).
Explanation:
This location allows for the brake system to efficiently transfer the braking force to the wheels, slowing down or stopping the vehicle. The brake drum is mounted in a cast spoke wheel assembly can be quite specific to those studying automotive engineering or mechanics. The correct answer is that the brake drum is mounted on the inboard side of the wheel hub.
The inboard mounting is crucial because it facilitates a more compact design and helps protect the brake drum from road debris and damage. Additionally, this configuration assists in heat dissipation, a critical factor in maintaining brake performance during extensive use.
