Question

Tank trailors are provided with $16wheels$ so as to:

• A. increase pressure on the road
• B. decrease pressure on the road
• C. support the weight of the tank
• D. none of the above

Answer 1

The correct option is B

decrease pressure on the road

1. Thus, pressure exerted on a given surface depends upon the following factors:

a. Pressure is directly proportional to the force applied on the surface.

b. Pressure is inversely proportional to the area of cross-section of a surface.

2. Tank trailors are provided with $16wheels$ because it increases the area of contact with the ground by distributing the weight uniformly, thus decreasing the pressure on the ground.

Hence, the correct answer is option (B) i.e. decrease pressure on the road
