Question

please select the correct answer (true or false)

increasing the surface area of the platform exposed to strong or gusty winds will decrease the machines stability.

true
false

Explanation:

Analyze the physical effect of wind on surface area

An increase in the surface area exposed to wind increases the aerodynamic drag force (wind load) acting on the platform according to the relation:

$$F_d = \frac{1}{2} ho v^2 C_d A$$

Determine the impact on machine stability

A larger wind force \(F_d\) acting at the elevated platform height increases the overturning moment about the base of the machine, which directly decreases the machine's overall stability.

Answer:

• True (Correct answer)
• False
