1-16. An eyebar is connected to a fitting by means of a 15-mm-diameter finished pin, as shown in Fig. 1-9. (a) What maximum pull P in the bar can this pin resist in shear if its allowable shearing stress s, is 100 MPa? (b) If a tensile stress s, of 112 MPa is permitted in the round bar, what diameter d will give the bar the same strength in tension as the pin has in shear
