Final answer:
The percentage of weight each leaf spring carries per axle depends on the vehicle's weight distribution and center of gravity. A given example illustrates that 52% of a passenger car's weight is on the front wheels, and another example shows how to calculate the force constant for individual springs in a pickup truck's suspension.
Step-by-step explanation:
The question regarding the percentage of weight that each leaf spring carries per axle deals with the concept of weight distribution and the center of gravity (CM) of a vehicle. Specifically, we can refer to an example where a passenger car with a 2.5-m wheelbase has 52% of its weight on the front wheels. This means that the center of gravity is located closer to the front axle. To find the location of the CM with respect to the rear axle, we can use the ratio of weight distribution and the wheelbase.
In the case of a pickup truck with four identical springs and a given force constant, each spring supports an equal share of the weight. If the total force constant of the truck's spring system is 1.30 × 105 N/m, and it has four identical springs, then the force constant for each individual spring would simply be a quarter of the total force constant.
