The unit for rotational inertia
What is kilogram meters squared
a force acts perpendicularily to a lever arm 15 cm away from the point of rotation. How much torque would be applied if the force acting upon the lever arm was 15 newtons?
2.25 newton meters
rF*sinθ or Ia
What is the equation for torque
v=rw only when
An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an external force.
The unit for torque
What is Newton Meters
A torque of 400 newton meters is generated on a door that is 1 meter wide. Assume the force is applied in the middle of the door, 0.5 meters away from the axis. How much force is required for the torque to be generated.
800 newtons
