An automotive plate clutch consists of two pairs of contacting surfaces with asbestos friction lining. The maximum engine torque is 200 N-m. The coefficient of friction is 0.35. The inner and outer diameters of friction lining are 200 and 300 mm respectively. Clamping force is provided by nine springs, each compressed by 4 mm to give a force of 700 N, when the clutch is new. (i) What is the factor of safety with respect to slippage when the clutch is brand new? (ii) What is the factor of safety with respect to slippage after initial wear has occurred? (iii) How much wear of friction lining can take place before the clutch will slip?

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.
