shear joint. The ultimate shear stress of the material is 300 MPa. Assume, safety factor on shear stress is3. The cross-sectional area of the bars FD and BD are 2000 mm?,yield strength of the bar material is 210 MPa.Find the following: For the given information in the figure, calculate the required diameter of the pin for joint D.а. b. The bars are made with a material that has yield strength of210 MPa in tension or compression. Calculate the axial stress in bar DF and bar BD, and the safety factors for the bars. с.Is the structure safe ?
