गोड्डा. गोड्डा वासियों के लिए नए साल की शुरुआत एक और बड़ी खुशखबरी के साथ हुई है. झारखंड सरकार ने जिले को सिंचाई के क्षेत्र में मजबूत बनाने की दिशा में एक अहम कदम उठाया है. 9 जनवरी, यानी गुरुवार को झारखंड सरकार की कैबिनेट बैठक में मुख्यमंत्री हेमंत सोरेन ने गोड्डा जिला अंतर्गत सैदापुर में निर्माणाधीन वियर योजना के लिए 3873.454 लाख रुपये के पुनरीक्षित प्राक्कलन को प्रशासनिक स्वीकृति प्रदान कर दी है.

The Jharkhand high court also directed the Senior Superintendent of Police, Ranchi to look into the security of the ED office in Ranchi. The Jharkhand High Court has paused a probe by Ranchi Police against Enforcement Directorate (ED) officers, a day after a similar move by the Supreme Court in a Kolkata Police case over the I-PAC office raids. The high court also directed the Senior Superintendent of Police, Ranchi, to look into the security of the ED office in Ranchi. "It is made clear that if any untoward incident occurred in the said office, the SSP, Ranchi, will be held liable for that," it noted, adding that the court cannot be a mute spectator in such cases. The strong remarks follow tensions between the state police and the federal agency after ED officers found their Ranchi zonal office surrounded by police last morning. The night before, the state police had emailed the ED regarding allegations of coercion and assault against two of its officers, including an as...

Strength & Stability in Structural Engineering 🏗️ Structural engineering revolves around strength (ability to withstand forces) and stability (ability to remain steady without tipping or collapsing). These principles ensure that bridges, buildings, and towers remain safe and durable under different conditions. Key Aspects of Strength - Load Resistance – A structure must resist different forces: - Dead Load – The weight of the structure itself. - Live Load – People, furniture, vehicles. - Wind Load – Pressure caused by wind. - Seismic Load – Vibrations from earthquakes. - Thermal Load – Expansion and contraction due to temperature changes. - Material Strength – Engineers choose materials based on their properties: - Concrete – Strong in compression, weak in tension. - Steel – High strength and flexibility. - Timber – Lightweight but needs protection from moisture. - Brick & Masonry – Durable but heavy. - Structural Components – Different parts contribute to strength: - Beams ...

Core Principles of Structural Engineering - Strength & Stability – Structures must support their own weight and external forces (wind, earthquakes, traffic). - Durability – Buildings should last for decades without major issues. - Safety – Engineers ensure structures can withstand extreme conditions without collapsing. - Efficiency – Materials are used wisely to balance cost, strength, and sustainability. Types of Structures Designed Structural engineers work on a variety of projects, including: - Buildings – Houses, skyscrapers, stadiums. - Bridges – Suspension, arch, cable-stayed designs. - Tunnels – Underground passages for transport and utilities. - Dams – Large barriers to control water flow. - Towers & Telecommunication Structures – Like radio towers and wind turbines. Structural Loads & Forces A structure faces several forces and loads: - Dead Load – Weight of the structure itself. - Live Load – People, furniture, vehicles. - Wind Load – Pressure exerted by wind. -...
