Analysis The total mass of the car with its components and driver (70 kg) is about 270.3 kg. This value is used in the Von Mises stress analysis. Figure 4 to 9 show the location of the forces and clamps for static, acceleration, braking, cornering, front stiffness and rear stiffness analyses respectively. As shown in Figure 4, for static case analysis, only the major components that were placed inside the chassis were considered. These weight components were the weight of the engine and the weight of the driver. The mass of the engine was 20 kg while the mass of the driver was approximately 70 kg which were about 200 N and 700 N respectively. The clamps were placed at all the parts of the chassis where the brackets were attached. The weight of the driver was distributed to the seat mountings while the weight of the engine was distributed to the engine mountings. The loads were directed downwards. In Figure 5, for acceleration analysis, only the major weight components of the car inside the chassis which were the engine and driver were considered. The loads and clamps were placed at the same parts of the chassis as in the static analysis. However, the loads were directed backwards, since, during acceleration, the engine and driver experience inertia whereby the mass of the driver and engine tends to stay where it was (pushing backwards) when the car was moving forward. In Figure 6, for braking analysis, the loads and clamps were placed at the same parts of the chassis as in the acceleration analysis. However, the loads were directed forward as during braking, the engine and driver experience inertia whereby the mass of the driver and engine tends to continue moving forward when the car is being stopped from moving forward.
