+//To find diameter of hand wheel
+clc
+//Given:
+d=50,p=12.5,D=60,R=D/2 //mm
+W=10*1000,P1=100 //N
+mu=0.15,mu1=0.18
+//Solution:
+//Calculating the helix angle
+alpha=atan(p/(%pi*d)) //radians
+//Calculating the tangential force required at the circumference of the screw
+phi=atan(mu) //Limiting angle of friction, radians
+P=W*tan(alpha+phi) //N
+//Calculating the total torque required to turn the hand wheel
+T=P*d/2+mu1*W*R //N-mm
+//Calculating the diameter of the hand wheel
+D1=T/(2*P1*1000)*2 //m
+//Results:
+printf("\n\n Diameter of the hand wheel, D1 = %.3f m.\n\n",D1)
