WebThe force pushing - or pulling - a body along a horizontal surface can be expressed as. Q = F cos α (1) where. Q = force moving the body in horizontal direction (N, lb) α = angle between force F and horizontal plane. The force acting in vertical direction can be calculated as: P = (F2 - Q2)1/2 (2) where. P = force acting in vertical direction ... Steps for Solving Static Friction Problems Step 1: Identify the coefficient of static friction between the surface and the object. Step 2: Find the normal force acting on the object. Step 3: Find the maximum value of the static friction by multiplying the coefficient of static friction and the normal force.
