Determine unknown forces using D'Alembert's principle applied to a free-body diagram, for three blocks of masses M1, M2 and M3 are connected by a flexible but inextensible string as shown in the figure assuming the co-efficient of friction between blocks M1, M2 and inclined surface to be u=0.25. Find the acceleration of the masses and tension in 5 kg T 5 ks 30 the string. 15 kg
