The 137-kg industrial door with mass center at g is being positioned for repair by insertion of the 3° wedge under corner b. horizontal movement is prevented by the small ledge at corner a. the coefficients of static friction at both the top and bottom wedge surfaces are 0.56. calculate the rightward force p' which would remove the wedge from under the door. assume that corner a does not slip for your calculation of p', but then check this assumption; the coefficient of static friction at a is 0.62.
