Force constant of rear suspension of car

Click For Summary
SUMMARY

The discussion centers on calculating the force constant of a car's rear suspension using Hooke's Law. Given a 110 kg load in the trunk causing a 13 cm decrease in bumper height, the formula F = kx is applicable, where F is the force exerted by the weight, k is the spring constant, and x is the displacement. The force can be calculated as the weight of the box (mass multiplied by gravitational acceleration), leading to a definitive method for determining the spring constant.

PREREQUISITES
  • Understanding of Hooke's Law and its application in mechanics
  • Basic knowledge of force, mass, and gravitational acceleration
  • Ability to perform unit conversions (e.g., kg to Newtons)
  • Familiarity with displacement measurements in physics
NEXT STEPS
  • Calculate the force exerted by a 110 kg mass using F = mg
  • Explore the application of Hooke's Law in different mechanical systems
  • Investigate the impact of varying spring constants on vehicle dynamics
  • Learn about suspension system design and optimization techniques
USEFUL FOR

Automotive engineers, mechanical engineers, physics students, and anyone involved in vehicle suspension design and analysis.

Can anyone help with the formula set ups for this ?

A 110 kg box is loaded into the trunk of a car. If the height of the car's bumper decreases by 13 cm, what is the force constant of the rear suspension ?

Sounds like a Hooke's law problem, F = kx, k is the spring (force?) constant, and x is the displacement from the equilibrium position, how much the spring is compressed or stretched. Does this help?
