A robotics engineer wants to estimate the pressure a heavy exploration rover exerts on a sandy testbed when parked stationary on one of its landing pads. She records the following measurements for a single landing pad:
| Measurement | Value |
|---|---|
| Force (weight) supported by the pad | 720 ............ |
| Area of the pad in contact with the sand | 180 cm2180 \text{ cm}^2180 cm2 |
Complete the table by writing the correct unit for weight on the dotted line.
State the name of a piece of equipment that the engineer could use to measure this force directly.
Suggest a method the engineer could use to find the contact area of the textured landing pad.
State the formula linking pressure, force, and area.
Calculate the pressure, in N/cm2\text{N/cm}^2N/cm2, that the landing pad exerts on the sand.
