    Lateral Force from Electrostatic Attraction Force?

    A grounded metal plate is held equidistant between two connected and charged plates. Assume the mechanism to slide the center plate in or out has a coefficient of friction of 0.0 Since the vector forces applied to the center plate are normal to the surface, is there a lateral/shear force when...

    Lateral Friction forces?

    A roadway is designed for traffic moving at a speed of 78 m/s. A curved section of the roadway is a circular arc of 190 m radius. The roadway is banked - so that a vehicle can go around the curve - with the lateral friction forces equal to zero. How would I go about finding the angle at which...
