WebMay 10, 2024 · we know that young modulus =Stress/strain and A rigid body is defined as one manifesting zero strain regardless of applied stress so Y=stress/0 Y= infinite (because any number devived by zero is infinite, 1/0= infinite) Infinite.because there will be no strain for a perfectly rigid body.so stress/strain equals young module.here strain /zero ... WebSECTION (A) : ELASTIC BEHAVIOUR LONGITUDINAL STRESS, YOUNG MODULUS A 1. The Young’s modulus of a wire of length L and radius r is = Y N/m2. If the length and radius are reduced to L/2 and r/2, then its Young’s modulus will be : (A) Y/2 (B) Y (C) 2Y (D) 4Y A 2. The graph is drawn between the applied force F and the strain (x) for a thin ...
Webthe strongest born in the human body the femur the thigh bone is so strong it can withstand at least six to seven times your own body weight and yet take a fall from your chair just the right way and you can easily break that bone how can something be so strong and yet so weak at the same time we have seen in previous videos that if you have an object which … WebYoung's modulus for a perfectly rigid body is zero. 14%. B Bulk modulus is relevant for solids, liquids and gases. 14%. C Rubber is less elastic than steel. 29%. D Young's modulus and shear modulus are relevant for solids. 43%. E None of the above. 43%. Solution: Correct answer is (a) Young's modulus for a perfectly rigid body is zero.

WebExample of Modulus Of Rigidity. The following example will give you a clear understanding of how the shear modulus helps in defining the rigidity of any material. Shear modulus of wood is 6.2×10 8 Pa. Shear modulus of steel is 7.2×10 10 Pa. Thus, it implies that steel is a lot more (really a lot more) rigid than wood, around 127 times more! pata hard drive laptopWebStatement-1: Young\\'s modulus for a perfectly plastic body is zero Statement-2: For a perfectly plastic body, restoring force is zero. pata hierroWebSep 1, 2024 · Ans.5 Young’s modulus is given by,\(Y=\frac{\sigma}{\varepsilon}\) Where, Y is Young’s Modulus \(\sigma\) is stress \(\varepsilon\) is strain But a perfectly rigid body will have no strain, no matter how much stress is applied to it. Thus, if the strain is zero, Young’s modulus will be infinite for a rigid body. pata hdd interfaceWebAnswer: Young's modulus is the stress to strain ratio of an object.
