The handles of a table-drawer are equidistant from the sides of the drawer and are distant c from each other. Show that it will be impossible to pull the drawer out by pulling one handle if l le mu c where l is the length of the drawer from back to front and mu is the coefficient of friction [Hint : Consider a force applied at inclination theta with the knob of the handle. Apply conditions for translational and rotational equilibrium. Hence show it is possible to draw when tan theta ge (l-muc)/(mu^(2)c+2mu^(2)x+2muI) Since tan theta is positive, l ge mu c]
