+clear ; clc ; close ; // Clear the work space and console
+
+// GIVEN DATA
+t_s = 0.49 ; // Human body is in contact with 60 Hz power for 0.49 sec
+r = 100 ; // Resistivity of soil based on IEEE std 80-2000 
+
+// CALCULATIONS
+// For case (a)
+v_touch50 = 0.116*(1000+1.5*r)/sqrt(t_s) ; // Maximum allowable touch voltage for 50 kg body weight in volts
+
+// For case (b)
+v_step50  = 0.116*(1000+6*r)/sqrt(t_s) ; // Maximum allowable step voltage for 50 kg body weight in volts
+// Above Equations of case (a) & (b) applicable if no protective surface layer is used
+
+// For metal to metal contact below equation holds good . Hence resistivity is zero
+r_1 = 0 ; // Resistivity is zero
+
+// For case (c)
+v_mm_touch50 = 0.116*(1000)/sqrt(t_s) ; // Maximum allowable touch voltage for 50 kg body weight in volts for metal to metal contact
+
+// For case (d)
+v_mm_touch70 = 0.157*(1000)/sqrt(t_s) ; // Maximum allowable touch voltage for 70 kg body weight in volts for metal to metal contact
