Calculating support forces on each tire

Click For Summary
SUMMARY

The discussion focuses on calculating the support forces on each tire of a stationary truck carrying two uniform crates, each weighing 350kg, in the bed of a 1500kg truck. The total mass of the system is 2200kg, leading to a gravitational force of 21560N. To find the support forces, participants suggest determining the center of gravity and calculating torque, emphasizing that the force distribution is not uniform across the tires.

PREREQUISITES
  • Understanding of static equilibrium principles
  • Knowledge of torque calculations
  • Familiarity with gravitational force equations
  • Basic concepts of center of gravity
NEXT STEPS
  • Study static equilibrium in mechanics
  • Learn how to calculate torque in various scenarios
  • Research methods to determine the center of gravity for irregular shapes
  • Explore force distribution analysis in vehicle dynamics
USEFUL FOR

Students in physics or engineering courses, mechanical engineers, and anyone involved in vehicle load analysis or stability assessments.

Homework Statement



Two uniform crates of 350kg are placed in the bed of a stationary 1500kg truck. Determine the support forces at each of the wheels

The dimensions are only around the horizontal axis

Homework Equations


Fx = n1 + n2 -M1g -m2g-m3g

T= Dmg


The Attempt at a Solution



Thats about where I am at, I am just looking for a hint,
 
Physics news on Phys.org
Add mass of crates and truck -> find gravitational force -> divide by 4 (force is split over 4 tires)

If it was uniform that would be right but its not uniform. This is what I came up with:

Find center of gravity, Calculate torque, using that the sum of all forces has to equal total mass it should cancel out, any thoughts?
