Machine Design A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ. The half of the length of the spring if cut off and the remaining spring is acted upon by the same axial force. The maximum shear stress in the spring in new condition will be τ/2 2 τ 4 τ τ τ/2 2 τ 4 τ τ ANSWER DOWNLOAD EXAMIANS APP
Machine Design The plasticity is the property of a material which enables it to Retain deformation produced under load permanently Regain its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resist fracture due to high impact loads Retain deformation produced under load permanently Regain its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resist fracture due to high impact loads ANSWER DOWNLOAD EXAMIANS APP
