4. A ring made of 2.5 cm diameter steel bar carries a
pull of 10 kN. Calculate the maximum tensile and compressive stresses
in the material of the ring. The mean radius of the ring in 15 cm.
A 3/8-inch diameter bolt is subjected to a 2,085-lb tensile load. The bolt passes
through a very thick plate to restrain it. Compute the tensile stress in the bolt.
Your Answer:
100 kN
A bracket in the form of a plate is fitted to a column by means of
four rivets of the same size, as shown in Fig. A load of 100 kN
is applied to the bracket at an angle of 60° to the horizontal and
the line of action of the load passes through the centre of the bot-
tom rivet. If the maximum shear stress for the material of the rivet
is 70 MPa, find the diameter of rivets. What will be the thickness
of the plate if the crushing stress is 100 MPa?

- The stress in a wire of diameter 2 mm if a load of 100 gm is applied to a wire.arrow_forwardFigure 2.1. shows two long plates with same material and equal width w=20 mm that are subjected to a uniaxial tensile load o. One of the plates has a single small central hole with diameter 4mm and another plate has two small holes with a distance of 8mm from each other. The holes are perpendicular to the external tensile load. Develop a computer code (or simulation model) and analyze how stresses will be distributed at the tip of the holes in these two plates for different values of 0. 4mm Figure 2.1. 8mm 4mmarrow_forwardA rectangular bar is notched on two sides as shown in Fig. 5.9a.

If the ultimate stresses are 400 MPa in tension, 320 MPa in shear and 640 MPa in crushing, find the minimum force per pitch which will rupture the joint.
