Chassis is a main body frame that acts as the backbone of a vehicular structure like tricycle. As the main frame of the structure, most of the components' parts for the vehicle are attached to it; such as the seat, skirting, footrest platform, basket and other sections that made up the tricycle's body to form a complete structure. Thus, a chasis is required to exhibit a high level of rigidity and durability as it needs to support all the load on it. Therefore, it is essential to ensure that this particular structure must have a quality and practical design to withstand the stress-strain of the applied load.
