Context[]

Red Line = 40pxl | 0.192

Green Line = 113pxl | 0.5424

Blue Line = 9pxl | 0.0432

Moment of inertia = pi*4.32^4/4

Moment of inertia = 17.0964084881

Section modulus = 17.0964084881/2.16

Section modulus = 7.91500392968cm^3

Yield strength of rebar is 420 MPa

Bending moment = 420*7.91500392968

Bending moment = 3324.30165047Mn

Green Line = 0.5424 meters

Linear force = 4*3324.30165047/0.5424

Linear force = 24515.4988973 Newtons or 2.50158152013 Tons of force (Class 5)

Now you have to divide by the arm movement

Movement = 0.98960168588 meters

Force = 2.50158152013/0.98960168588

Force = 2.52786707604 Tons (Class 5)
