3D printers in an Atal Tinkering Lab (ATL) provide immense benefits to educational institutions from various perspectives:
1. Design Perspective:
• Students can visualize and create physical prototypes of their ideas, improving their spatial and design-thinking skills.
• It allows students to design complex structures, such as models of buildings, mechanical systems, or scientific diagrams.
• Encourages learning of Computer-Aided Design (CAD) tools, fostering technical skills.
2. Innovation Perspective:
• 3D printing allows young innovators to quickly prototype and test their ideas, reducing development time.
• Promotes experimentation by enabling cost-effective creation of models for societal solutions, such as prosthetics or sustainable products.
• Drives creativity by giving students the freedom to iterate on their ideas.
3. Thinking Perspective:
• Enhances problem-solving abilities by converting abstract ideas into tangible outcomes.
• Encourages critical thinking, as students analyze design flaws and improve their models iteratively.
• Develops logical thinking and teamwork through collaborative projects involving 3D printing.
Overall Impact: Using 3D printers in an ATL enhances hands-on learning, bridges the gap between theory and practice, and equips students with skills in design, innovation, and critical thinking that are essential for solving real-world problems.
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
In the adjoining figure, $\triangle CAB$ is a right triangle, right angled at A and $AD \perp BC$. Prove that $\triangle ADB \sim \triangle CDA$. Further, if $BC = 10$ cm and $CD = 2$ cm, find the length of AD.
