Question 42
Easy

Figure 1 shows an automated robotic crawler climbing a wind turbine mast to service the rotor hub.

A diagram showing an automated robotic maintenance crawler climbing vertically up a wind turbine mast to a height of 12.4 m. The crawler has a mass label of 75 kg.

The crawler has a mass of 75 kg.

The crawler ascends through a vertical height of 12.4 m.

The gravitational field strength, g=9.8 N/kgg = 9.8 \text{ N/kg}g=9.8 N/kg.

Calculate the change in the gravitational potential energy of the crawler.

Use the equation:

ΔEp=m×g×Δh \Delta E_p = m \times g \times \Delta h ΔEp​=m×g×Δh
