Calculate the torque exerted by the car around the back wheels

Click For Summary
SUMMARY

The discussion centers on calculating the torque exerted by a car around its back wheels when the car is elevated at a 10° angle. Given the car's length of 3.08 m, mass of 1129 kg, and the center of mass located 1.54 m from the front end, the torque can be calculated using the formula T = R * F, where R is the distance from the pivot point (back wheels) to the center of mass and F is the force due to gravity. The force is determined by multiplying the mass by the acceleration due to gravity (F = mass * g), resulting in a torque value expressed in Newton-meters (N·m).

PREREQUISITES
  • Understanding of torque and its calculation
  • Knowledge of basic physics concepts, specifically forces and moments

Homework Statement



A mechanic jacks up a car to an angle of 10◦
with the horizontal in order to change the
front tires. The car is 3.08 m long and has a
mass of 1129 kg. Its center of mass is located
1.54 m from the front end. The rear wheels
are 0.4 m from the back end.
Calculate the torque exerted by the car
around the back wheels. The acceleration of
gravity is 9.81 m/s2 .
Answer in units of N · m.
