A worker can supply a maximum pull of 150 lbs. on a cart which has a handle set an angle of 40degree above the horizontal. what is the coefficient of friction if he can just move a total load of 1500lbs. ?

  • physics - ,

    Normal force at maximum moveable load
    = 1500 - 150sin40 = 1404 lb

    Coefficient of friction (static)
    = (tangential force)/(normal force)
    = 1500 cos40/1404 = 0.818
