Question

15 Question 2 a) The safety coefficient of the rope obtained by using 100 pieces of wire with a diameter of 2mm 10. Since the tensile stress is 200 kg/cm2, what is the load to be carried by the rope? 6) How much is the shear stress that occurs against the 3000kg force affecting the M14 bot the connection shown in the figure below? in

Answer 1

wire 2mm Sol: a) diameter of safety factor of 100 wie = 10 Stress (Tensile) 200 kg len 200X9.81 10-4 19.62 MPa wad stress = Area stress x Area Load = **1962 x (10 * £/(218'] safely freter Load 61.6 KN 61.6 KN u by rope Hence wad to be carried would be b) Me 4 diameter of balt f = 3000 x 9.81 29.43 KN force 29-43 I+(14 415²) 2 shear stress = Area shearing 4 191 27 MPa - Therefore shear stress is 191.27 mPa.
