7. Communication and Collaboration: In earlier times, engineers had limited means of communication and collaboration. Large projects required coordination among various stakeholders, and the lack of advanced communication tools could hinder project management and implementation.

8. Ethical and Environmental Considerations: Historically, ethical and environmental considerations were less prominent in engineering practice. Today, engineers must address concerns related to sustainability, environmental impact, and social responsibility, reflecting a broader awareness of these issues.

Overall, engineers throughout history have faced a range of challenges that have driven innovation and advancement in the field. The evolution of engineering practices has been shaped by the need to overcome these obstacles and adapt to changing conditions and demands.
