Nissan Armada 2025-2026 Service and Repair Manual: What is Energy
Equation that expresses kinetic energy [EK]
EK = 1/2 ● m ● v2
[m: mass in kg, v: velocity in m/s]
The equation shows that the kinetic energy is proportional to the mass and the square of velocity. In an accident, not all of this kinetic energy will be absorbed as damage to vehicle or the other object.
The energy of the object gets transformed into different energy as well as heat, sound, friction and change in the vehicles position by spinning.
Depending on the amount of force acting on an object on a vehicle construction will depend on how far the absorption will be in the vehicle body structure.
We will be looking at force and different types of deformations that can occur on an object, part or structure.
Damage Diagnosis: Fundamental
What is force
Force causes the shape of objects and state of motion to change.
Equation that expresses force [F]
F= m + a
[m: mass in kg, a: rate of acceleration in m/s2]
The equation explains the ...
Deformations on Panels
Elastic Deformation
If you apply light force to a panel and it deforms lightly, and once released. it returns to its original shape or form, this is called elastic deformation. If the panel gets elast ...

Measurement with Three-dimensional Measuring Equipment
Measure the dimensions using three-dimensional measuring equipment and compare the measurements with the vehicle body alignment dimensions to identify any deformation in each direction. Several types of equipment are available, such as universal jig type, universal measuring type, laser type, comput ...

DISASSEMBLY
NOTE:
Never remove the torque member and brake pad when disassembling and assembling the cylinder body.
Remove the sliding pin bolt, and remove the cylinder body from the torque member. Refer to Removal and Installation.
CAUTION:
Fix the brake pad at suitable tape so that the brake pad ...
