Dimensions of shear stress
WebUnder compression, it can will island a stress or about 160 106 Pa before breaking. Assume that a femur (thigh bone) is 0.50 m long, and calculate the amount of compression this bone can withstand before breaking. arrow_forward Bone has a Youngs modulus of 18 109 Pa. WebThe maximum shear stress is then calculated by: where b = 2r is the diameter (width) of the cross section, I c = πr 4/4 is the centroidal moment of inertia, and A = πr 2 is the area of the cross section. Shear Stresses in Circular Tube Sections A circular tube cross section is shown in the figure below:

WebIn such a case, when deforming forces act tangentially to the object’s surface, we call them ‘shear’ forces and the stress they cause is called shear stress. The SI unit of stress is the pascal (Pa). When one newton of force presses on a unit surface area of one meter squared, the resulting stress is one pascal: WebThe dimension of shear stress is: [ S h e a r s t r e s s] = [ F] [ A] = [ M L T − 2] [ L 2] = [ M L − 1 T − 2] EXPLANATION: Option 1: Dimension of volume is [L 3 ]. Option 2: Dimension …
