SITUATION 3: A shelf is being designed to hold crates having a total mass of 1840 kg. Two support steel rods in the figure will hold the shelf. Assume that the center of gravity of the crates is at the middle of the shelf and the shelf is rigid. Neglect the weight of the shelf and the rods. 1. Calculate the required diameter (mm) of the rod the stress is limited to 110 MPa. 2. If the diameter of the rods is 25 mm, calculate the vertical displacement (mm) of the rod-shelf connection. 3. If the diameter of the rods is 25 mm, calculate the horizontal displacement (mm) of the rod-shelf connection. ASNWERS: 12.36 mm; 0.5018 mm; 0.1613 mm Circular rod 20° Shelf 1200 mm Two rods support the shelf

A steel riser pipe hangs from a drill rig located offshore in deep water (see figure). (a) What is the greatest length (meters) it can have without breaking if the pipe is suspended in the air and the ultimate strength (or breaking strength) is 550 MPa? (b) If the same riser pipe hangs from a drill rig at sea, what is the greatest length? (Obtain the weight densities of steel and sea water from Table M, Appendix I. Neglect the effect of buoyant foam casings on the pipe.)
The boom in the figure below (Figure 1) weighs 3000 NN and is attached to a frictionless pivot at its lower end. It is not uniform; the distance of its center of gravity from the pivot is 40%% of its length. Make a free-body diagram of the boom. The boom attaches to the building at dot A. The center of gravity of the boom is indicated by dot B. The guy wire attaches to the boom and holds the load at dot C. Find the tension in the guy wire. Find the horizontal component of the force exerted on the boom at its lower end. Find the vertical component of the force exerted on the boom at its lower end

Rope BCA passes through a pulley at point C and supports a crate at point A. Rope segment CD supports the pulley and is attached to an eye anchor embedded in a wall. Rope segment BC creates an angle of ø = 64.0 ° with the floor and rope segment CD creates an angle 0 with the horizontal. If both ropes BCA and CD can support a maximum tensile force Tmaz = 165 lb. what is the maximum weight Wmar of the crate that the system can support? What is the angle e required for equilibrium?
