Homework Help: Static equalibrium?

  1. Nov 9, 2009 #1
    1. The problem statement, all variables and given/known data
    A student gets his car stuck in a snow drift. Not at a loss, having studied physics, he attaches one end of a stout rope to the vehicle and the other end to the trunk of a nearby tree, L = 12.2 m away, allowing for a small amount of slack, W = 0.400 m. The student then exerts a force F on the center of the rope in the direction perpendicular to the car-tree line,
    If the rope is inextensible and if the magnitude of the applied force is 406 N, what is the force on the car? (Assume equilibrium conditions.)
    2. Relevant equations
    Sum of the forces?

    Tryed sum of the forces i dont know really how to calculate the tensions(if thats what your supposed to do. any help will be appreciated

    Hi Chuck 86! :wink:
    Well, that should have worked …

    call both the tensions T (they'll be the same), and use geometry togehter with the fact that the sum of the forces on the centre of the rope will be zero.

    (or draw a vector triangle )

    What do you get? :smile:
