The worker presses on a shovel weighing 8 kg. What is the pressure the shovel exerts on the ground

The worker presses on a shovel weighing 8 kg. What is the pressure the shovel exerts on the ground if its tip measures 0.6m 0.002m.

To calculate the pressure of the used shovel on the ground, we use the formula: P = F / S = m * g / (L * B).

Variables and constants: m – mass (m = 8 kg); g – acceleration due to gravity (g ≈ 10 m / s2); L is the length of the tip (L = 0.6 m); B is the width of the tip (B = 0.002 m).

Let’s perform the calculation: P = m * g / (L * B) = 8 * 10 / (0.6 * 0.002) ≈ 66.7 * 10 ^ 3 Pa (66.7 kPa).

Answer: The pressure of the used shovel on the ground is 66.7 kPa.
