Consider a 1500 kg car chassis that supports its mass evenly among four suspension springs, one for each wheel, that compress 10 cm when the car is at rest. 1,500 kg Suspension springs in a typical car 10 cm Free length 1/4 mg Each spring supports about 1/4 the weight of the car. 1. Draw a free-body force diagram of the chassis showing the gravitational and elastic forces that are in equilibrium. What are the values of these forces? Show your work. 2. Use the diagram to calculate the spring constant k that is required to support one-fourth of the mass of the car when depressed by 10 cm. Show your work.
