Final answer:
The support perpendicular to the lid at a specific instant of an industrial garbage container can be calculated by dividing the total weight of the container by the width of the lid. In this case, the support perpendicular to the lid is 120 N/m.
Step-by-step explanation:
The support perpendicular to the lid at a specific instant can be found by dividing the total weight of the garbage container by the width of the lid. In this case, the weight of the lid is 60 N and the width is 50 cm. Converting the width to meters, we have 0.50 m. So, the support perpendicular to the lid at a specific instant is:
Support perpendicular to the lid = Weight of the lid / Width of the lid
Support perpendicular to the lid = 60 N / 0.50 m
Support perpendicular to the lid = 120 N/m
