The Big Duel vs Steel Structures Practice

The Big Duel The Bid Duel is a fun addictive game where you can test your math skills. You can choose between 3 game modes and play 1vs1 or 1vsTime Game Modes: - Math - Bigger/Smaller - Shapes Choose between math calculations like: * Addition * Subtraction * Multiplication * Division Choose hardness and play 1vs1 on 1 device or against the time. Let your kids train their math skills with lot of fun and nice animations (Blueprint). Have fun How To Play? Game Mode - Math You will get a math calculation and 3 different results, press the right result to move the rocket to earth. Game Mode - Big/Small You will get a math calculation and a random number in the middle button (that is NOT the right result). Now you must find out if the right result of the calculations is BIGGER or SMALLER than the number in the middle button. Game Mode - Shapes You will see a random shape and you will get 3 different results. Only one result is the right side amount of the shape. Press it to move the rocket to earth. (Circle has 0 sides, Triangle has 3 side)

Steel Structures Practice is an educational application designed to help students understand and practice the principles of structural steel design and analysis. The app emphasizes structured learning through chapter-wise quizzes, mock tests, and daily quizzes aligned with standard steel structures curricula. Users can practice questions from individual topics, attempt mock tests for comprehensive assessment, and monitor their performance using statistics. The app supports self-study, classroom learning, and examination preparation for civil and structural engineering students. Topics Included 1. Introduction to Steel Structures Properties of structural steel, grades of steel, advantages and disadvantages, and steel sections. 2. Structural Steel Components Beams, columns, tension members, compression members, plate girders, and built-up sections. 3. Connections in Steel Structures Bolted, riveted, and welded connections, types of welds, eccentric connections, and connection design principles. 4. Design of Tension Members Net and gross section area, design strength, failure modes, slenderness ratio, and splicing. 5. Design of Compression Members Buckling behavior, effective length, Euler’s formula, column curves, built-up columns, lacing and battening. 6. Design of Beams Bending strength, shear strength, lateral torsional buckling, section classification, web buckling, and bearing strength. 7. Plate Girders Flanges and web behavior, stiffeners, end bearing stiffeners, design procedure, and economical proportions. 8. Roof Trusses Types of trusses, loads on trusses, analysis methods, member design, and connections. 9. Industrial Buildings Industrial sheds, purlins, bracing systems, portal frames, crane girders, and load combinations. 10. Design Philosophy and Codes Limit state design, working stress method, load and resistance factors, IS 800 code provisions, safety factors, and serviceability criteria. 11. Steel Building Components Base plates, anchor bolts, gusset plates, cleat angles, stanchions, and rafters. 12. Corrosion Protection and Maintenance Corrosion mechanisms, protective coatings, galvanization, fire protection, inspection, maintenance, and retrofitting. Key Features Chapter-wise practice quizzes Mock tests for full syllabus assessment Daily quiz for regular practice Performance statistics to track progress Content aligned with steel structures syllabus Simple and distraction-free interface Steel Structures Practice is suitable for civil and structural engineering students preparing for examinations and strengthening conceptual understanding through consistent practice.
