- 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 hollow drill pipe for an oil well (sec figure) is 6,2 in. in outer diameter and 0.75 in. in thickness. Just above the bit, the compressive force in the pipe (due to the weight of the pipe) is 62 kips and the torque (due to drilling) is 185 kip-in. Determine the maximum tensile, compressive, and shear stresses in the drill pipe.A thin-walled aluminum tube of rectangular cross section (sec fig me) has a centerline dimensions b = 6.0 in. and b = 4.0 in. The wall thickness t is constant and equal to 0.25 in. Determine the shear stress in the tube due to a torque T = 15 kip-in. Determine the angle of twist (in degrees) if the length L of the tube is 50 in. and the shear modulus G is 4.0 x 106 psi.

If this shaft is connected to a similar shaft, 1 m long, through a 10-bolt rigid flange coupling, determine the minimum standard bolt diameter if the pitch circle diameter of the coupling is pcd = 450 mm and the allowable shear stress in the bolts should not exceed 55 MPa.1.Determine the equivalent torsional stiffness of the shaft assembly.Q2. A mild steel shaft transmits ‘P’ kW at ‘N’ r.p.m. It carries a central load of 900 N and is simply supported between the bearings 2.5 metres apart. Determine the size of the shaft, if the allowable shear stress is 42 MPa and the maximum tensile or compressive stress is not to exceed 56 MPa. Power P in KW= 25 , Speed N in rpm=150
- The stepped shaft shown in the figure isrequired to transmit 600 kW of power at 400 rpm.The shaft has a full quarter-circular fillet, and thesmaller diameter D1 =100 mm.If the allowable shear stress at the stress concentrationis 100 MPa, at what diameter D2 will thisstress be reached? Is this diameter an upper or alower limit on the value of D2?A machinery uses a helical tension spring with wire diameter of 3 mm and coil outside diameter of 35 mm. The spring has 9 total coils. The design shear stress is 500 MPa and the modulus of rigidity is 82 GPa. Determine the force that causes the body of the spring to its shear stress in N. Consider ground ends.A closely coiled helical spring is to carry a load of 500N. Its mean coil diameter is to be 10 times that of the wire diameter. Calculate these diameters if the maximum shear stress in the material of the string is to be 8OMN/mA2.
- A torsion dynamometer is fitted on a turbine shaft to measure the angle of twist. It is observed that the shaft twists 1.5° in a length of 5 metres at 500 r.p.m. The shaft is solid and has a diameter of 200 mm. If the modulus of rigidity for the shaft material is 85 GPa, find the power transmitted by the turbine.An overhang hollow shaft having inside diameter 0.5 time outside diameter, carries a cast iron pulley having 800N weights and 900mm diameter, at 250mm from the nearest bearing. The pulley is driven by another pulley mounted on the shaft placed bellow it, to transmit 35kW at 400r.p.m. The belt ends are vertical and parallel; if the ratio of tensions in belt is 3 and the permissible shear stress for material of shaft is limited to 200MPa, determine the diameters of shaft.The length of the smooth circular shaft with a solid cross-sectional area of 315nm2 is 1 meter. Instead of this shaft, it is desired to use an evacuated circular-section shaft with a wall thickness of 3 mm with the same length and weight. For these two cases, compare the angles of rotation that would occur if a moment M = 600 (N.m) was applied to the end of the shaft made of material G-80 GPa.
