Following are steps for calculation:
a) Enter load in NEWTON or N/m depending on type of loading.
b) Enter the length of beam in METER.
c) Enter Young's Modulus in Gpa. For example Young's modulus of Mild steel is about 210 Gpa.
d) Enter Area moment of Inertia in CM^4 by using below formula for different cross section of beam. (Note: 1 CM^4 = 10000 MM^4)
e) After entering the above data, results will be calculated automatically in output display box.
