Final answer:

The total work done on construction materials during a crane lift can be calculated by considering the force applied at different segments of the lift process.


Explanation:

The total work done on the construction materials can be calculated by breaking down the process into segments and applying the work-energy principle. In this scenario, work is done when an object is moved against a force, resulting in a change in energy.

In the given crane scenario, the total work done is the sum of the work done in each segment of the lift:

  1. Work done in the first 10 m where force changes from 0 to 10 kN.
  2. Work done in the next 40 m where a constant force of 10 kN is applied.
  3. Work done in the last 10 m as the force decreases back to 0 N.

The total work done is the sum of the work done in each segment, taking into account the force applied and the distance over which it's applied.
