A belt drive consists of two V-belts in parallel, on grooved pulleys of the same size. The angle of the groove is 30°. The cross-sectional area of each belt is 780 mm2 and the coefficient of friction between the belts and the pulleys is 0,12. The density of the belt material is 1,4 Mg/m3 and the maximum safe stress in the material is 7,5 MN/m2. Consider centrifugal tension. Calculate: 2.1 The mass of the belt per metre length. 2.2 The centrifugal tension (Tc). 2.3The maximum tension (T1). 2.4 Tension on the slack side (T2).

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.
