Axial Load

When a bar of the uniform cross-section is acted by a load, such that the load acts along the longitudinal axis of the bar, such kinds of loadings are known as axial loadings. In general terms, a load is an external force acting on a component. An axial load acts perpendicular to the geometric cross-section of the component. Based on the direction of the application of the load, an axial load can be tensile or compressive. The analysis of bodies under the action of axial loads is generally studied under the branch of mechanics, known as statics.

The two solid steel shafts shown in the figure are connected together using gear wheels. The length of the CD shaft is Lcd=2 m and the length of the AB shaft is LAB= 1.5 m. The radius of gear C is rc=45 mm and the radius of gear B is rB= 90 mm. The CD and AB shafts rotate freely in the bearings on which they are supported. Also, shaft AB is fixed at point A. Each shaft has a diameter of 20 mm and a shear modulus of G=65 GPa. When a torque of T= 450 N.m is applied to the CD shaft from the D end;a) Calculate the torsion angle on shaft AB. (Write your result in radians.)b) Calculate the total rotation (torsion angle) of the D end of the CD shaft. (Write your result in radians.)
The layout of transmission shaft carrying two pulleys B and C and supported on bearings A and D is shown in Figure below. Power is supplied to the shaft by means of a vertical belt on pulley B, that is then transmitted to pulley C carrying a horizontal belt. The maximum tension in belt on pulley B is 2.5 kN. The angle of wrap for both the pulleys is 180o and the coefficient of friction 0.24. The shaft is made of plain carbon steel 30C8 (Syt=400 N/mm2) and the factor of safety is 3. Determine the shaft diameter on strength basis.
