+//INPUT DATA
+P1=180// PULL APPLIED TO THE BODY IN NEWTONS
+theta=30// ANGLE AT WHICH P IS ACTING IN DEGREES
+P2=220// PUSH APPLIED TO THE BODY IN NEWTONS
+//Rn= NORMAL REACTION
+//F= FORCE OF FRICTION IN NEWTONS
+//U= COEFFICIENT OF FRICTION
+//W= WEIGHT OF THE BODY IN NEWTON
+//==========================================================================================
+//CALCULATION
+F1=P1*cosd(theta)// RESOLVING FORCES HORIZONTALLY FROM 3.16(a)
+F2=P2*cosd(theta)// RESOLVING FORCES HORIZONTALLY FROM 3.16(b)
+// RESOLVING FORCES VERTICALLY Rn1=W-P1*sind(theta) from 3.16(a)
+// RESOLVING FORCES VERTICALLY Rn2=W+P1*sind(theta) from 3.16(b)
+// USING THE RELATION F1=U*Rn1 & F2=U*Rn2 AND SOLVING FOR W BY DIVIDING THESE TWO EQUATIONS
+X=F1/F2// THIS IS THE VALUE OF Rn1/Rn2
+Y1=P1*sind(theta)
+Y2=P2*sind(theta)
+W=(Y2*X+Y1)/(1-X)// BY SOLVING ABOVE 3 EQUATIONS

+//OUTPUT
