Can a Sedan Trunk Carry a Load of 600 Jin?

[MacClayton]

A sedan cannot carry a load of 600 jin, as the general load-bearing capacity of a sedan is around 500 jin. Carrying 600 jin would exceed the sedan's load limit. The following are the impacts of overloading on a car: 1. Reduced braking performance and increased unsafe stopping distance: Many factors affect a car's braking distance, and changes in the car's load directly influence the length of the braking distance. Overloaded cars have increased inertia, resulting in longer braking distances. The extension of the unsafe stopping distance can easily lead to traffic accidents. 2. Shortened lifespan of leaf springs and reduced vehicle maneuverability: Due to overloading, the leaf springs are subjected to excessive force and continuous bouncing during driving, which shortens their lifespan. Additionally, the excessive load causes the vehicle to sink overall, reducing the ground clearance and diminishing the car's ability to pass through certain areas. 3. Accelerated tire wear and deformation: Car tires are designed and manufactured based on the total weight of the vehicle, with a considerable safety margin. However, when a car is overloaded, the tires bear excessive weight and deform. The increased friction also leads to a shorter tire lifespan.
