the magnitude of the tongue produced by a 3.0n force applied to a door at a perpendicular distance of 0.25 m from the hinge

  • physics - ,

    You seem to be confusing tongues with torques.

    Review the definition of tor

  • physics - ,

    Torque is force times distance from an axis of rotation (the hinge in this case)

    Multiply the two numbers you have been given

  • physics - ,

    T=(f)(d)
    torque=force x distance

    T=40NM
    D=30cm=0.3m
    F=?

    T=(f)(d)...F=T/D
    F=40NM/0.3m
    =133.3N

  • physics - ,

    0.37
