and are connected by a short piece of string as shown in the following figure. If the
coefficients of friction between the blocks and the plane are respectively u=0.15 and
AB = 0.25, determine (a) the angle of inclination of the plane for which sliding will
impend, and (b) tension in the string. Take W-Wg 30 N.
