The strain energy will be higher in which shaft under the same torque mcq If the hollow shaft is to store 25 % more energy than the solid shaft when transmitting torque, what must be its internal and external diameters? Assume the same maximum shear stress applies to both shafts. Failure theories help predict the limits of materials under stress or strain, which is crucial for designing safe structures and preventing catastrophic failures. The main failure modes include ductile failure (significant deformation), brittle failure (sudden breakage), fatigue failure Sep 26, 2025 · A higher Modulus of Rigidity results in greater torsional stiffness, meaning the shaft will experience less angular deformation under an applied torque. The strain energy in the form of elastic deformation is mostly recoverable in the form of mechanical work. Mar 14, 2016 · When a shaft of length l is gradually twisted through an angle under the influence of a Torque T. Understand the implications for torque and speed transmission. Then, the work done in twisting shall be equal to the strain energy due to torsion (U). This energy is a result of the internal shear stresses and strains produced in the material during the twisting action. ratio of strain energy for solid and hollow shaft subjected to same torque if outside diameter of both shaft is equal. 4. 1000+ Strength of Materials MCQ PDF arranged chapterwise! Start practicing now for exams, online tests, quizzes, and interviews! May 26, 2024 · The strain energy stored in a body, when the load is gradually applied, is (where σ = Stress in the material of the body, V = Volume of the body, and E = Modulus of elasticity of the material) This tutorial explains elastic strain energy, strain energy density, and their importance in elasticity analysis, including formulas and practical applications. These expressions for stored energy will then be used to solve some elasticity problems using the energy methods mentioned in the previous section. 1. Nomenclature c = distance from neutral axis to outer fibre (m) E = Young's Modulus (N/m 2) F = Axial Force (N The strain energy stored in a solid circular shaft, under pure torque, per unit its volume (take max shear stress = q and modulus of rigidity = C) is expressed as. Oct 22, 2025 · Get Strain Energy Stored in Shaft Multiple Choice Questions (MCQ Quiz) with answers and detailed solutions. When the applied torque is removed, the stored strain energy helps the shaft return to its original shape, provided the material remains The energy absorbed during this work of deformation is known as strain energy. Download these Free Strain Energy MCQ Quiz Pdf and prepare for your upcoming exams Like Banking, SSC, Railway, UPSC, State PSC. 9 STRAIN ENERGY IN TORSION Let a shaft of length l be under the action of torque T. Key Points to Remember Here is the list of key points we need to remember about “Theory of Failure”. Problems on Shafts in Series and Parallel: Test your knowledge with problem-solving exercises involving shafts connected in different 6. Strain energy due to bending load:- 4. 2. The work done (equals the total strain energy U) is given by:- Strain Energy The external work done on an elastic member in causing it to distort from its unstressed state is transformed into strain energy which is a form of potential energy. This method requires direct contact between the sensor and the measured shaft, and calculates the shaft power by measuring the strain generated by the shaft under torque[2]. Explore strain energy, its types, loading conditions, failure theories, and applications in engineering. Strain energy due to shear load:- 4. Oct 22, 2025 · Get Strain Energy Multiple Choice Questions (MCQ Quiz) with answers and detailed solutions. To understand why the Modulus of Rigidity is the primary factor, let's delve into the relationship between the torque (T) applied to a shaft and the resulting angle of twist (θ). In this article, we’re going to discuss: What is Strain energy? Strain energy formula: Strain energy units: Strain energy for different loadings: 4. Download these Free Strain Energy Stored in Shaft MCQ Quiz Pdf and prepare for your upcoming exams Like Banking, SSC, Railway, UPSC, State PSC. 2 Elastic Strain Energy The strain energy stored in an elastic material upon deformation is calculated below for a number of different geometries and loading conditions. Traditional shaft power measurement often uses contact measurement methods, such as torque sensor measurement. 8. 3. 5 days ago · Short Answer: The strain energy due to torsion is the energy stored in a shaft or circular member when it is twisted by an external torque. Important notes, please refer to them. Strain energy due to axial load:- 4. wztfvfe yjw ohcnqw ztrz igorvi gphnlv wibp taajzsn lazct updad jhrogk edrz mnkp jkcgdgvc scfve
