Subtopic: Mechanics of tractor chassis

Question Statement:

A tractor traveling on a $10^\circ$ slope has total weight $22\text{ kN}$. The normal force pressing perpendicular to the slope in kN is $22 \cos 10^\circ \approx 22 \times 0.9848 = 21.67\text{ kN}$. The value (rounded off to two decimal places) is:

Answer Key:

21.67

Step-by-Step Solution & Explanation

$F_n = W \cos 10^\circ = 22 \times 0.984808 = 21.666\text{ kN} \approx 21.67\text{ kN}$.
