A hole is to be punched out of a plate having a shearing strength of 275 MPa. The compressive stress in the punch is limited to 345 MPa. If the plate is 6.5 mm thick, determine the diameter of the smallest hole that can be punched. 0.5 mm 1 mm 2 mm 0.8 mm. 1.6 mm Two stepped shaft are rigidly fastened together and support a vertical load of 5 kN as shown in Figure below. The upper shaft is steel having length 100 mm and cross-sectional area 50 m2. The lower shaft is brass having The modulus of elasticity of steel is E-200 GPA and brass is E-100 GPa Determine the average normal stress in the brass when the load is applied 133.3 MPs 106.7 MP 62.5 MP 150 MPs SAN 4
