The figure shows a plate having a width of 400 mm and thickness of 12 mm is to be connected to another plate by 34 mm diameter bolts as shown in the figure. Assume diameter of holes to be 2 mm larger than the diameter of the bolts. Use A 36 steel plate with yield strength Fy = 248 MPa and minimum tensile strength Fu = 400 MPa. For a chain holes extending across a part in any diagonal or zigzag line, the net width of the part shall be obtained by deducting from the gross width the sum of the diameters or slot dimensions of all holes in the chain and adding, for each gage space in the chain, the quantity S24g where S is the longitudinal center to center (pitch) of any consecutive holes, in millimetres and g is the transverse center to center spacing (gage) between fastener gage lines in millimetres. If a = 60 mm, c = 150 mm and d = 100 mm. Determine the nearest value of “b” so that the net width along bolts 1-2-3-4 is equal to the net width along bolts 1-2-4. Determine the nearest value of the net area for tension in the plates. Determine the nearest value of P so that the allowable tensile stresses will not be exceeded.

The figure shows a plate having a width of 400 mm and thickness of 12 mm is to be connected to another plate by 34 mm diameter bolts as shown in the figure. Assume diameter of holes to be 2 mm larger than the diameter of the bolts. Use A 36 steel plate with yield strength Fy = 248 MPa and minimum tensile strength Fu = 400 MPa. For a chain holes extending across a part in any diagonal or zigzag line, the net width of the part shall be obtained by deducting from the gross width the sum of the diameters or slot dimensions of all holes in the chain and adding, for each gage space in the chain, the quantity S24g where S is the longitudinal center to center (pitch) of any consecutive holes, in millimetres and g is the transverse center to center spacing (gage) between fastener gage lines in millimetres. If a = 60 mm, c = 150 mm and d = 100 mm.
- Determine the nearest value of “b” so that the net width along bolts 1-2-3-4 is equal to the net width along bolts 1-2-4.
- Determine the nearest value of the net area for tension in the plates.
