Line of pull of a MB plough is 15° with the horizontal and is in a vertical plane which at an angle of 12° with the direction of travel plane which is at an angle 12° with the direction off travel. Calculate the side draft.

a) 234.12 kg
b) 219.06 kg
c) 212.45 kg
d) 200.09 kg

Answer: c
Explanation: Draft = P * cos 15° * cos 12°
Side draft = P * cos 15° * sin 15°
Or, P = \(\frac{Draft}{cos15°*cos12°}=\frac{1000}{cos15°*cos12°}\) = 1058 kg
Side draft = 1058 * cos15° * sin 12°
= 212.45 kg.
