In this practice, you will apply a quadratic inequality to model the load that can be withstood by a freight elevator. You need to solve the inequality, it will have two solutions that represent the maximum and minimum loads that can be withstood by the elevator. In this application, you will use only natural numbers, as mass cannot be negative. To carry out the practice, you will be given a freight elevator with a basket, an electric motor, a scale and masses of different values.
